I JUST DELETED MY LIVE MYSQL SERVER

I DON'T KNOW IF WE HAVE BACKUPS

How a web application works

Too much stupid today..

Client: "Our server is almost full, fix it"

Me: "Okay, you can upgrade the VM, or I can see if theres anything that can be cleaned up?"

C: "Clean it up"

Me: *Finds 5 extra MySQL DB's that amount to 50-60GB in total*

Me: "Well I can remove some of your extra databases, and some of the local backups, as they're also backed up offsite. They're currently unused and dated back to the beginning of 2017, everything is out of date anyways."

C: "No"

Me: "Okay, is there a reason?"

C: "No"

Me: "Okay, so we'll upgrade the VM?"

C: "No"

Me: "I'm sorry, but those are really your two options"

C: "Just fix it"

What in the ducking fuck !@#$#%?
If you're so fuggin smart, then why do they pay me?
I'm clearly stupid and unable to read your mind.

Yesterday I managed to optimize a query...
Went from 43 seconds to 0.0702 seconds.

For some reason mysql decided to copy the data of 4 huge tables into a temp table and do its operations there... (the copying to temp tale took 42/43 seconds)

Two composite indexes later and I saved the company hours of time over the course of a few months.

Feels good.

For a flipping two hours the code wasn't working. Then I saw this single dot instead of comma...

NOOOOOOOOOOOOOOOOOOOOOOO

It nearly give me an heart attack: mysequel

When I was an intern, I wrote a very heavy MySQL query with multiple joins. Quite frustrated, I asked for some help from one of my seniors.

He came by on my desk and told me, "Explain your query!".

I was completely blank-faced O_O.

After a few moments, the senior grabbed this hopeless bastard's keyboard and typed "EXPLAIN" in the beginning of the query; and then ran it.

I thought he was being hard to me.

Fun fact: Michael Widenius named "MySQL" after his daughter My. When MySQL was acquired by sun, he decided to start a new open source database, "MariaDB", named after his second daughter Maria.

This guy is (partially) responsible for two of the largest databasesystems in the world.

Imagine his daughters apply for a database engineering job one day. During application process: "One of the largest databases in the world was named after me..." 😂

Forever Alone :'(

Who killed MySQL?

When we found out MySQL utf8 isn't actually utf8..... it's a proprietary subset of utf8 that only includes up to Unicode 255..... and there is a separate "utf8mtb4" that is actual utf8.

I remember some years ago when a professor asked -
"What is the difference between SQL and MySQL?"

And one of the students answered -
Uh... I don't know... SQL is more like a general SQL and MySQL is a personal SQL...

:|

I have to let it out. It's been brewing for years now.

Why does MySQL still exist?

Really, WHY?!
It was lousy as hell 8 years ago, and since then it hasn't changed one bit. Why do people use it?

First off, it doesn't conform to standards, allowing you to aggregate without explicitly grouping, in which case you get god knows what type of shit in there, and then everybody asks why the numbers are so weird.

Second... it's $(CURRENT_YEAR) for fucks sake! This is the time of large data sets and complex requirements from those data sets. Just an hour through SO will show you dozens of poor people trying to do with MySQL what MySQL just can't do because it's stupid.

Recursion? 4 lines in any other large RDBMS, and tough luck in MySQL. So what next? Are you supposed to use Lemograph alongside MySQL just because you don't know that PostgreSQL is free and super fast?

Window functions to mix rows and do neat stuff? Naaah, who the hell needs that, right? Who needs to find the products ordered by the customer with the biggest order anyway? Oh you need that actually? Well you should write 3-4 queries, nest them in an incredibly fucked up way, summon a demon and feed it the first menstrual blood of your virgin daughter.

There used to be some excuses in the past "but but but, shared hosting only has MySQL". Which was wrong by the way. This was true only for big hosting names, and for people who didn't bother searching for alternatives. And now it's even better, since VPS and PaaS solutions are now available at prices lower than shared hosting, which give you better speed, performance and stability than shared hosting ever did.

"But but but Wordpress uses MySQL" - well then kill it! There are other platforms out there, that aren't just outrageously horrible on the inside and outside. Wordpress is crap, and work on it pays crap. Learn Laravel, Symfony, Zend, or even Drupal. You'll be able to create much more value than those shitty Wordpress sites that nobody ever visits or pay money on.

"But but but my client wants some static pages presented beside their online shop" - so why use Wordpress then? Static pages are static pages. Whip up a basic MVC set-up in literally any framework out there, avoid MySQL, include a basic ACL package for that framework, create a controller where you add a CKEditor to edit page content, and stick a nice template from themeforest for that page and be done with that shit! Save the mock-up for later use if you do that stuff often. Or if you're lazy to even do that, then take up Drupal.

But sure, this is going a bit over the scope. I actually don't care where you insert content for your few pages. It can be a JSON file for all I care. But if I catch you doing an e-commerce solution, or anything else than just text storage, on MySQL, I'll literally start re-assessing your ability to think rationally.

Stop telling everyone it's *your* SQL!

My local MySql: "root"/""

So I gave this guy access to a database and phpMyAdmin and then I get this:

Him: hello??? i cant make databases i have no privilages
Me: Use tables instead of databases...
Him: I need to make databases
Me: Why?
Him: 1. my votes plugin 2. my ftop plugin 3. my forums 4. my new forums 5. my new forums (he runs a minecraft server fml)
Me: You don't need databases for all of those, you can use tables, that's a massive waste
Him: idc i would rather have databases

AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!

Can I borrow Your SQL!!!!

Tonight I want to try to setup an openvpn server with mysql based authentication because I'd love to somehow setup/become a vpn provider.

Of course there's a huge ass legal part but let's first make sure I know the technology of the top of my head!

Just ranting this out because I'm excited 😊

At the moment I'm trying to optimize a slow old MySQL query from a project I made several years ago. The execution time is in excess of 55 seconds. Not good :(

After about an hour of experimenting I finally set a good index and reduced the time to < 3 seconds.

Chuffed :)

It would be really FUCKING great if NodeJS or mysql could give me a FUCKING shout or ERROR MESSAGE when one of the parameters I'm giving is not the RIGHT FUCKING DATA TYPE INSTEAD OF THROWING A RANDOM ERROR THAT DOESN'T INDICATE A WRONG MOTHERFUCKING DATA TYPE. Five FUCKING hours of debugging later.

Lol this guy literally asked me to use My OWN sql

..Sure, I..I can try that.

Am I the only one who reads mysql as "my sequel"?

Who killed mysql?

MySQL Found on Jupiter by NASA :D

- John says that your sql is not working fine, but his does, so use his sql.
- but boss, MySQL ...
- I said use his sql

:-/

Dad came home with this today. Yaay :D

Mom response to printing to console.

How to deal with mysql errors :

Option 1 : Write better queries
Option 2 : ALTER TABLE

This is one of the most unexpected, silly and ridiculous behaviors of MySQL: it doesn't support LIMIT in sub-queries, however it perfectly supports it in sub-sub-queries. WTF.

MySQL issues...

Select * from World where "someone" like '%you%';

No result!

Damn...

Who killed MySQL?? Your guesses... Was it Ruby, a fan of postgres? 😂

Job title :
"PHP and MySQL Programmer"

Job description :
"We are looking for a Flash Developer with a high level of proficiency developing ActionScript solutions.... bla bla Development in a 2D and 3D environment"

doesnt say ANYWHERE what is require to know in php nor mysql

EDIT: actually it does but why would they put php and mysql programmer if thats not the main things they are looking for

Job interview.

Head of development: "I'm looking for the perfect php developer with perfect MySQL knowledge."

Me: "We'll ok. Good look with finding that unicorn. I think we are done here."

The problem with some people is that they are the gatekeepers for other people's careers and that they are begging to be bullshitted: "Yes of course I am the best of all php developers! And I don't only know MySQL but am pretty awesome in YourSQL as well!" As if I want to work in a team posers.

If I could!

Task:
- Replace a 4 year old PHP API.
Old API:
- PHP script writing PHP scripts to /var/www/ for every endpoint needed
- Answers everthing with 200 (not even 404)
DB:
- MySQL 5.6
- ~ 1000 Tables, NO FUCKING FK's
Documentation:
- "Wasn't worth the effort"
New API:
- Not allowed to behave any different

Someone else's SQL

Apparently `= NULL` is not a thing in mysql, instead you have to use `IS NULL`... Took me a while to figure out why the fuck my query wasn't returning any results.

Spend several days decoding API legacy code from the guy who got paid shitload of money and then stumble on the piece of code that shows he isn't even aware there is a count function in SQL (or rowCount in PDO)

:)))))

Working on a database priorly designed and maintained by some private agency.

The fuck I'm dealing with!

Boolean values stored as 'TRUE'/'FALSE'. It's varchar, my dudes.

There are no FK relations. Just the values of IDs in a column.

There are no indexes, all on just the PKs, nothing else. Nothing.

Null, what's that? I'm dealing with 'N/A', my dudes.

Unique key, what's that? The table which stores users has all the fields nullable. Email is not unique ( even though that's the required behaviour).

ALL the numeric values are stored as varchar. Varchar, my dudes. Varchar. '1', '1.1'

And finally, the good ole, 1 table to rule them all. Normalisation, fuck that.

And what's the root cause of all this? My PM used to hand them Excel sheets she maintains on her local system. FTW. I don't have a enough explanations.

YAY a JOIN query (MySQL) just ran successfully at the first try for the first time of my life!! I never understood joins but slowly getting there I guess :)

I hate that, not only did this error happen, but they weren’t smart enough to hide the MySQL stack trace

NO DJANGO, YOU'RE WRONG! THE TABLE DOES FUCKING EXIST I CAN FUCKING SEE IT AND ACCESS IT AND FUCKING ADD AND TAKE AWAY FROM IT!

MySQL Workbench - User friendliness at its worst.

So I'm in the middle of the website migration that was made in Wordpress.

Just made a database dump and decided to take a look at it cause it looked really big for a site that only needs internal management. Found out they use contact form plugin which stores binary of attachments directly in database..

And people ask me why I hate Wordpress and so called Wordpress devs..

MySQL should have a recycle bin. I just deleted whole "user" table by mistake... Forgot to add where clause properly... Had to restore 2 days old backup copy. I just hope no accounts were created or someone changed their password in last 2 days....

Me as Junior Dev doing mysql first time, specifically INSERT test data to test db, sucess on first try.

My Senior co-worker says: WOW, Baby's first INSERT...... that sounds so wrong out of context xD

I always cringe when I hear people pronounce MySQL as "MySequal" 😂

Internship Rant #2

I can't believe I'm hating my job right now. It sucks because I have never coded in javascript and they expect me to code in javascript. I don't even know what I am doing, but I'm trying my best. I kinda have something already, but the worst part of it is that my boss comes in once in a while and sits beside me looking at my screen and of course, he expects me to tell him what I have been doing and what progress I have done. It's stressful cause I specifically told him that I have never coded in JavaScript and he still thinks I can get things done in a few days.

Perks of new job:
- I can take a bath there whenever I want
- gr8 bathroom 11/10
- gr8 heater, no need to have my hands shaking all the time
- workspace is nice and everyone has an extension so my phone and laptop are always on full charge
- flexible work schedule
- easy access to company files hehehe including credentials

Anyways, so I have to deal with this for three months.

Many thanks MySQL. Really a good way to implement a driver. Go fuck yourself.

When migrating from MySQL server to MariaDB and having a query start returning a completely different result set then what was expected purely because MariaDB corrected a bug with sub selects being sorted.

It took several days to identify all that was needed on that sub select was “limit 1” to get that thing to return the correct data, felt like an idiot for only having to do 7 character commit 😆

Okay so this happened ages ago (nearly five years) but this suddenly came to my mind again.

It was in the first year of my study (currently in my 5th and last year).

I was experimenting around with php and mysql during some free hours. All the insert,delete and so on statements worked perfectly find except for one update statement. Started to debug of course and after a little while of no results I was like "oh yeah right, something like logs exists of course". Looked in the logs but nothing. No matter how I altered my code (rewrote it numerous times for some 'clean starts') it just would not run the update statement.

Alright, time for some class mate help. After multiple hours of debugging with a few classmates, there was still no result at all.

Time to bring in one or more teachers. After hours of debugging, still no result even with the help of a few good teachers.

Decided to give it a rest for that day.

Two weeks later it still was not updating anything/working and I finally gave up.

Till today, I still have no clue what went wrong and it still bugs me from time to time :/

Good morning people. Holidays in Malta. Trying to forget html, css, php, MySQL and JavaScript 🙂 ... But my heart is with you 😂

Good job.

MySQL has the absolute worst error messages.

"You have an error in your SQL syntax; check the manual that corresponds blah blah near '(some random code line)'".

How vague can you be? It doesn't help that I always find the error in a completely different place to where the message says it is.

MySQL almost gave me a fright 😂😂😂

My first times today:
First time a droplet on Digital Ocean.
First time Nginx.
First time trying to separate mail and website servers.
First time using UFW firewall.
First time Ubuntu webserver.
First try all alone configuration of my webserver.
First time installing all the stuff I need on my own, like MySQL, PHP and so on.
First time only SSH access from the beginning.
First time deployment from bitbucket.

Do you have any advise what I should think about. Or what software I will need. Or what I should think about.

MySQL fell down the stairs again and dropped tables all over the datacenter

the affected servers tried to notify me in advance but spamd wasn't able to scan their messages so IT JUST DIDN'T SEND THEM

EVEN IF IT COULD, NAMED COULDN'T RESOLVE ANY MX RECORDS

BECAUSE BEFORE MYSQL CRASHED IT CONVERTED /ETC/RESOLV.CONF INTO AN INNODB TABLE

(AND THEN DROPPED IT)

(ON PURPOSE)

So last night i was dealing with some mysql query issues trying to grab some complex data from a relational database and ended up giving up.

This afternoon i was about half-asleep going to nap, not even thinking about the code and randomly came up with the solution.

A few hours later i made the changes and it works as intended.

Anyone else solve code subconsciously ? 😂😂😁😁

Screw MySQL/MariaDB. Who the fuck thought not to document that utf8 is only 3 bytes and not unicode capable. You have to use utf8mb4 for it to work. Fuck those idiots that don't want to admit they made a mistake and put this info in a footnote on a pricy documentation piece.

I messed up carelessly in production. Learnt how SQL queries bite you in the ass when it knows you are under pressure.

Was hosting an online quiz kinda thing during my college techfest. Tens of thousands of people participating.

Using MySQL as database and thousands of queries were being executed. Everyone were pretty excited as the event just opened up.

None of the teams could solve one particular level. Turns out the solution was wrong and was asked by the organisers to change the solution for that particular level. Usual stuff, right?

Was too lazy to open up the web UI for the back office and so, straight ahead logged in to the MySQL server and ran the UPDATE query on the table consisting of the solutions.

It had been a couple of hours and the organisers came to me with a weird problem. There were no changes in the scoreboard for the last two hours. Everyone were stuck wherever they were. Weird, right?

I then realized.

Fk.

In that dreaded query, I had only run

UPDATE 'qa' SET answer = 'something'

leaving out the where clause, specifying the question to update, like

WHERE qno=13

As a result, solutions to all the questions were updated to the same answer. After hastily fixing everything back, I had the dreaded conversation.

Org: What was the problem?

Me: It was the cache.

Org: Damn thing. Always messes up.

Me: *sheepishly* yeah

Probably the most embarrassing moment in my life, wrt coding 😑

Working on another online pokemon game sort of thing and I'm super proud of myself because I just got the user registration, login, auth session, and logout done. Last time I tried making one of these damn things I didn't bother using a database and I tried making a complex user auth system using JSON files and God, I regret that now.

Now only a million steps to go (Including making the game)

*Opens code*
> Sees mysql_ bindings, XSS/SQL injection vulns
*Logs into webhost*
> Running PHP 5.4 by default
> Doesn't support PHP 7

Sadly, I'm sure this is a common scenario, particularly the webhost part

I was working on a very database heavy PHP app about six months ago. All database access was done directly, with hardcoded SQL strings.
I'd suggested switching over to an ORM during the upcoming major verson's rewrite, and FINALLY got approval to start integrating one.
The next week I'm told that I need to trash all the code I'd just written, since the decision to use an orm has been reversed.

The rationale? According to management, ORMs aren't "scalable enough for our application" and would "reduce developer productivity". I pointed out that we would be processing ~10 concurrent operations, maximum; I was told that the technically details didn't matter and the person I was working under had the final say because they'd worked at IBM, briefly, as an intern.

I stopped working on that project about two weeks later, thankfully.

fucking hosting company...

Just got a ticket back explaining that "the settings you want to make to your mysql database aren't possible with our hosting products". While they state in their FAQ that there are no restrictions applied. (We are talking about to possibility of using JOIN here!)

Ducking fuck.

I recently got a Sysadmin/Devops job at an Uber-like local startup.
After a few days in and with a 20% increase in daily API calls, we started getting "502 gateway error" for like half of the requests which was insane!
I double checked nginx, php-fpm, mysql, etc and in the end turns out that they log every app login session in a 680K row table in a mysql database and run a query every time to find out if the client was logged in or not!

°__°

spent 8 months building and customizing a vtiger database for work. tons of fun got it to a point where I have saved a ton of time for all the people that use the program. boss wants to have reports out of it each morning, so I showed him how to run reports and adjust entries. he didn't like the formatting of the report. so I set up the report to export to excel and took another 2 hours building a macro that formats the way he likes and prints the report for him. he used to take a month filling out paper work to get a report, now all he has to do is open a favorite on his web browser, make 3 clicks Then open an excel and type ctrl+r and it's done. he tells me it seems too complicated and is considering going back to the paper method...so frustrating.

Been taking a course on php and I'm currently working through a cms project. It's just so satisfying learning how all the data communicates from frontend to backend.

For PHP and MySQL devs, look about phinx.

Installed phpmyadmin from apt.

It has 2 errors in the source php files.

What?

When UserID is an int(3) in one table, and then text(10) in another. And then the monent you see that the Username field is stored in both tables ......🖕🖕🖕🖕

Who dafuq wrote this crap?!?!?!?

I added functions to create and delete categories on my cms project :) Its starting to come around.

$ mysql -uroot -p > file.sql instead of
$ mysqldump -uroot -p > file.sql

And not checking the result file before reinstalling my server 😭😭

I'm debugging someone else's 10 year old legacy .asp web application (shoot me now), and I'm trying to find the most recent records in a database table.

Why is the most recent record from September of last year?

Oh.

Because they're storing the datetime value as varchar (40).

Good thing they were smart enough not to waste disk space by using varchar (255)!

When someone decides to manually delete a user from a relational database that relies on that user to exist and expects everything to work out perfectly.

When the DB is like: Adieu :D

Awesome! New server!
With a newer version of MySQL
With new bugs on my websites

Seriously, this new version destroyed all the queries

Thanks Firebase! I dont have to buy a 5$ server and install php mysql etc.. anymore. It is super easy create something for one-page one-day side projects! I am so happy..

MySQL databases beginning with "test" in the name gives even people without login full access to its tables.

Somebody deleted all tables so we had to get a backup from out hoster.

Thanks MySQL.

I was having my after lunch coffee +reading devRant. I saw a rant about MySQL ("MySQL server has gone away" error).
It's spreading and no one can stop it!

Please use normalization. Don't store more than is intended in one field and use special characters to separate things. It would make future developers job easy.

*Runs MySQL benchmark on a new server*

Wtf mysql...

Oh hell yeah. I just spent a good few hours optimizing an ok mySQL query and made it so much better and faster. Inner join ftw!!

Ok. FUCK MySQL Workbench.
Most of our products built on MySQL and we just had enough of the tools that we are using for our mysql databases...
We decided to make our own tool :)

If it goes well, we plan to open source it. Would you guys be interested in it?
We planned the following features:
1. Schema editing
2. Schema versioning
3. Update/downgrade script generation to move easily between schema versions
4. Manual/auto sync
5. Might include our own replication solution too...

What do you think?

Twenty five goddamn minutes finding an incorrect quote mark in a bloody massive query of mySQL, I need a beer.

me and my boss plan to make a new feature to our system.

i model the database tables

he says that there are too many tables

i say its atomic and acid

he says to put all the columns in a single table

Having to deal with legacy code is fucking terrible. Worse yet when there is basically ZERO documentation and what little documentation there is, is wrong! Not just wrong, contradictory.

I have spent far too long trying to decipher what I need to make everything fucking work. Having to figure out if they used Gunicorn or UWSGI. Whether they used MySQL 5.6 or 5.7. Whether they wanted me bent over or crying on my knees.

when MySQL opens its updater terminal but does nothing but sit there in your toolbar

Why does MySql least and greatest functions return null if any of the arguments are null? Who was the genius behind the idea that it's the best way to implement it, and to change this behavior in a minor version?

Why does MySql return bigint when i convert a value to integer?

Why does MySql exist?

When I was really new to JavaScript, I wanted to create an image gallery with images which I stored in a MySQL database. Well, I did not really had a clue how to load all the image sources into my JavaScript to load the images. I also didn't know much about fetching an endpoint of my website to get the data asynchronously.

I also wasn't a good database architect at that time and my database had an image table wich was for the gallery. Within this table there were multiple columns for one image slider (there should be multiple sliders on one page in the gallery (I know... 🤢)).

So I ended up writing an PHP loop wich printed Javascript loops for each row in my images table. Within my JavaScript loop I created the sliders and set the images.

In my defense I can say: It worked. 😅

It hurts to remember this. And I hope you won't judge me.

Stupid fucking MySQL.
I thought I have fixed your fucking issue.
I'm hungry and I wanna go home. It's 19:38 now.
I was up since 05:00 and started coding at like 06:00.
Grrrrrrrrr fucking piece of shit.

// Or was it the laptop at home that I fixed this issue? I don't know anymore. I'll try to fix you at other day.

Me: "can you please send my credentials for the database?"

Hosting provider: "Yea sure... We will set it up on our servers in no time"

*5 mins later: provider sends mail to me*

Me: *looks at mail*

Also me: *NOTHING TO DO HERE*

Congrats to jweiland.net for not being able to support their customers.

DB relationships are giving me headache...just as regular relationships IRL

I made sure to commit all changes (from my desktop) before leaving my home for the weekend so I can continue my project at the parents house (going for a monthly visit)..

I arrived, synced all my changes to my laptop, all good and well, going perfect. Updated the bower components etc. Time to start some test runs so I started my localhost, opened my browser,..Ended up with a MySQL errors galore.. Unknown table this and that.. I forgot the export my MySQL database :'( #fml

I feel ridiculous. While learning SQL databases I ran a query that was supposed to fill up the database with test data for me to play with. The actual result?

8 GB and 330,000+ rows.

Keep in mind this database is on a remote server, so trying to delete it times out after thirty minutes. I’m submitting a ticket right now.

Ok! Ok! I got it, sheesh!!

when reviewing each other's code and sql queries is the most romantic way you can think of to spend the evening

I'm a MySQL developer. I dont know YourSQL.

SELECT REPLACE(@COMPANY, @SQL_DEVTEAM, SQL_DEVTEAM_NEW)

Had a teacher in high school who ordered us to learn MS Access, even tho most of us already knew MySQL... It was to learn about relations and the likes...
We spend way to long on that subject, because most of really didn't find the Access interface intuitive and she had to walk from table to table helping...
The only two finished the task where those who say screw it and used MySQL 😅

The moment when your forced to use mySQL after years of blissful coexistence with a noSQL workflow.

This is a true story. We had this subject, called “Web Design” (really, “design”), where we studied HTML, CSS, JavaScript, PHP and MySQL (confusing, right?). And when we get the PHP (e-)book, it was this old PDF (probably downloaded illegally) teaching the legacy 4.0 version of PHP. Anyway, when we had to develop the final project, the sane professor allowed us to use a newer version of PHP — 5.2, released on 2008. I had to follow the rules, so I developed probably the less secure web application I will ever develop. That means no protection from SQL injection, XSS vulnerable and a bunch of other security holes… And that’s how they liked it developed!

Boss: hey can you loop through all the entries in the data base (PHP) to make a menu of everything?

Me: me sure thing, shouldn't be a problem

10 min in playing with the database...and I remove the table...FUCK ME?!!??!!!

good thing we backed up the night before 😂😂

I remember it was Friday, 30 minutes before leaving the office when suddenly someone from the upper management directly asked for my help to mass update something as it is important. By that time our CMS is not capable of doing this so I had to do it straight in the live database.

It was an update query and I decided to type the query in notepad first. when i pasted it in the terminal i didn't noticed i missed the "where" part so i mass updated the status of all our records dating 3 years back.

fuck.. please take note it was on a Friday night.

Never have I been so satisfied as I am right now after having implemented a login and user account system with the ability to update user preferences with databases n' shit in PHP after only knowing PHP for a day.

Speaking of all that, do you guys know of any good place to make sure all my stuff is secure? No SQL injections n' the like.

Everything wrong with PHP, Wordpress, MySQL and Stackoverflow in a single screenshot.

Will I ever write a complex migration that runs flawlessly on the first go??? 😑😕

When mysql_query gets called inside of a loop that is inside of a loop.. While the could've used a one liner mysql command...

Best of all they don't think that this doesn't effect performance...

Tomorrow is my bd and I swear besides seeing my friends all I want is to find this bug.
</rant>

Just spent half an hour fixing a "bug" that turned out to be a wrong id in the db..

IT'S CAPS RANT TIME!
MYSQL ERRORS ARE SO USELESS! AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAHHHHH

I JUST WANT TO ADD A FOREIGN KEY BUT 'Cannot add foreign key constraint' KEEPS COMING UP, AND THE STACK OVERFLOW ANSWERS INDICATE THAT IT COULD BE -LITERALLY- ANYTHING!

THIS IS OF COURSE, AFTER PHPMYADMIN GIVES ITS OWN ERRORS FOR TRYING TO USE THE DESIGNER TO ADD THE RELATION. IT ONLY WANTS UNIQUE FOREIGN KEYS, DESPITE ONE OF THE MAIN USES OF FOREIGN KEYS BEING MANY-TO-MANY AND ONE-TO-MANY RELATIONS!

This just happened to me.

If you don't know how to do it the proper way, just throw something together. :D
Might not be pretty, but it works... (only took about 3 hours)

MySQL || NoSQL
Which is your prefer and why?

So I was waiting on a mysqldump for over a halfhour wondering why it was taking way to fcking long.

But then I saw I typed mysql -u user -p database > dump.sql

Instead of using the mysqldump command xD at moments like this you realize how important sleep is xD

Don't forget to set a password when installing mysql from cl #devmistakes

MySQL is Oracle's MS Access

MYSQL has gone away.....😔

I don't understand why someone who's totally sane and careful could forget to turn off MySQL general log over Christmas vacation. Of course Disk out of space caused us down time :/

When they want you to make stored procedures instead of an API... And there's no DBA.

Right, so I know I'm smashing this server right now, but I didn't even know this was possible!

I HATE MYSQL !

I just created an Oracle account just to comment on a mysql bug report in order to inform people to use mariadb as a fix ¯\_(ツ)_/¯

^w should delete back a word, not to the beginning of the line! This is broken because instead of readline, Oracle's mysql-client uses editline.

Yet why the fuck do you compile mysql-client with editLine wrapper that breaks the common keybindings?

Licenses is why. Oracle wants to avoid using GNU GPL, and readline uses just that, so they use editline since it has BSD. And they just don't seem to give a damn if it breaks usability.

Hello devs, I need help from database devs.

The company where I'm interning is a non IT company, so they planned to migrate to a SQL Database from their older MS Access Database.

Since I'm the only IT intern, I'm up against the major devs and hot shots from where my company outsources IT solutions.
They suggested SQL Express.

I have a meeting tomorrow with them, please help me so that I can get better results for my company.
Basically I have to question them about how their decision works better for our firm and why didn't we go for MySQL Enterprise Edition or anything which is much better and cheaper and such critical questions.
Please help me.

The Database would be used to store information about the products manufactured and their parts' history so that in future if there's a problem with the product, it can be looked up in the database so that there can be further replacement or repair processes.

Export data from a database that you've not modeled is a problem (sometimes), I just realized that this DB has two tables to storage cities, the main difference is the id, the other fields are the same in both tables, I hate that kind of people....

So, today timestamps within my database saved me. I have one titled "created_at" to indicate when the item was originally created.

Today a large client called up to complain that they have 296 bookings but only 288 menu choices (each booking has a menu choice). Basically, saying I'd "programmed it wrong [sic]" :(

After taking a quick look at the date the client originally added the menu and the date the missing bookings were created, I made a discovery.

It turned out the client was at fault. They had set an event (customers book events and bookings have a menu choice) live without associating the menu. This meant the event had been live without a menu for customers to book.

I simply compared the timestamps of the missing bookings to the date the menu was originally added. The customer most likely made the event live for period (I estimate ~45 mins), realised they hadn't associated a menu and then added it afterwards. Of course at this point it was too late as people had already booked.

No need for a huge email either. I condensed the above into a 5 sentence email.

Timestamps are soooo useful

A programme I have to maintain (and not allowed to optimise or change):

1) read input from serial connection
2) store data in MySQL database
3) every day convert to CSV
4) store on Windows file share
5) process CSV in access 2000
6) store in MsSQL database

When it was first developed, I said to te developer to store it straight from serial to MsSQL but out boss wanted it to follow the above spec.

He has now left and I have to maintain it

Rant at myself for being a moron.

Manually tried moving some InnoDB stuff around on a local server and corrupted a load of databases, with no backups since June 28th. Spent all day yesterday trying to recover with no luck 😑

Lesson learned: need to backup databases more regularly. Any good tools?

Working at a local seo sweat-shop as "whatever the lead dev does't feel like doing" guy.

Inherit their linux "server".
- Over 500 security updates
- Everything in /var/www is chmod to 777
- Everything in /var/www is owned by a random user that isn't apache
- Every single database is owned by root sql user
- Password for sudo user and mysql root user same as wifi password given to everyone at company.
- Custom spaghetti code dashboard with over 400 files in one directory, db/ api logins spread throughout these files, passwords in plain text.
- Dashboard doesn't have passwords, just usernames to login
- Dashboard database has all customer information including credit card stored in plain text
- Company wifi is shared by other businesses in the area

I suggest that I should try to fix some of these things.

Lead Developer / Tech Director : We're an SEO company, not a security company . . .

Do you know how MySQL got it's name? Well, it's a really interesting thing one should know. Atleast, I find it really amusing.

~Michael "Monty" Widenius is one of the founder of MySQL and one of his daughter's name is My(after whom MySQL was named).~

//rant

So i ordered myself a web server and am trying to get access to phpmyadmin.
I got generated username and password for the phpmyadmin login.
So i created mysql databases and database users, outside the interface, but that's fucking it, i need to create tables as well, can't do that without the interface, cuz NO ACCESS!

Fucking piece of shit service provider, they had one thing to do and they can't even fucking do it right. How dare they call themselves web hosts at all...

It's probably a badly configured config file but i can't access the file myself to start sorting this shit out, so i got to wait at least 12 hours till work hours to be able to contact with them and sort this shit out.

I gotta let this out. I apologize..

Why the FUUUCK does MySQL not let me log into my FUCNING ROOT USER AND THE OTHER USER I MADE...
I thought i fixed it a few days ago, but apparently not. Now im considering trashing this shitproject for a while.
*insert awesome words that illustrate extreme rage and a broken keyboard*

Fast Q:

What client with user interface for MySql are you guys using ?

I've alway pronounced it sequel but everyone I know swears it's SQL, so I say that now to fit in.

I feel like a spy, lying to my closest friends everyday...

FUCK! I've done this a fucking God fucking damn million fucking God fucking damn times fucking before! FUCK! FUUUUCK! FUUUUUUUUUCK!

The best part is that someone is going be paying me once it works............................... FUUUUU K!

I nearly missed the WHERE clause today. Only realized my mistake after I was about to close the SO tab and glanced at an answer below the one I read 😨

DELETE FROM 'users' WHERE id-1

Oops 😅 I meant id=1

Yes, it was a complicated Stored Procedure :-)

When every related field has a god damn different way of working with the data on hand..

For example:

`tht_date` ("Y-m-d", Date) - expiration date on the product, hence, there can be multiple of the same products with a different THT

`tht_alert` ("-2 months", varchar, DateTime modify mutation string) - sending an alert when this interval is hit, and being the activator of the tht_date field (unless value is "none")

`tht_minimum` ("28", integer, quantity of days before tht_date) - to lock them from being sent out/collected.

...

How would you expect this ×not× to become a friggin' spaghetti when trying to resolve the best row ID?

These values are in the wrong spot in the first place, then they also act entirely different in relation to eachother..

I hate the person that set this up, for doing this. When is the madness going to stop...

FFS!!

1) Writing data to database works just fine
2) Query reading back that same data returns null
3) Spend 3 hours to try figure out why that 4 year old select statement suddenly doesn't work anymore
4) Figure out mysql master stopped replicating to read slaves
5) Facepalm and cry a little

spend better part of my day processing about 400M rows of data with MySql, woo ain't no single line of code that can do that in 12hrs 😊

Gotta revise MySQL and Java for my IT Matura exam on Wednesday...

Reading/writing from/to files in a Java 8 manner,
LOAD DATA (LOCAL) INFILE "blah.csv" LINES TERMINATED BY "\r\n" DELIMITED BY ";' etc.,
Java Comparator,
clean Eclipse install...

No Internet, I'll have javadoc and mycli though.

Has anyone here used MongoDB for relational databases? I am trying to use MySQL with Node but I feel like the whole thing is a mess. There are some ORMs like Knex or Sequelize for MySQL but they are pretty crap. I am thinking if I should just move onto MongoDB instead of MySQL, at the same time I feel a little dirty to store relational data in a document store :(

I need to performance monitor our web app. I have been working on some speed improvments since some of our customers have complained. My boss wants me to be able to produce stats which he can use (and abuse) to highlight to customers that we have got quicker. I am currently looking at blackfire for PHP profiling to help with speeding things up but I need a top site overview for everything. Our stack is PHP (no framework), JS (jquery + vanilla), MySQL on Windows mainly. On premise solutions would be good since we don't traditionally run in the Cloud. Our system isn't SaaS and is installed on dedicated data centre servers or on premise

A developer walks into a bar and sees two tables. Says 'Can I join you?'

When it comes to choosing a database,  What is the best for a Java project?

1.SQL - MySQL
2.NoSQL- MongoDB

I just tried to updated mySQL on my development server, the mysql.user table is corrupted, all passwords got expired and i cant set new passwords because as i said, the user table is corrupted.

Our dev uses laravel and instead of doing a sum to get a total of a couple columns he is getting all values and manually counting them up in the php.
he keeps telling he cant improve and i cant work on his code because i know i will break the rest.
when i looked at the code i had the following feeling.

Once I deleted two tables in a production environment 🤬😩😱

So... We're going to totally rewrite one of our web applications at work. It's currently written using the .NET framework, and we're moving to Node.js instead. For me, that's absolutely wonderful! Outside work I practically only work with Node, so I'm happy. There is just one thing that's bothering me. My colleague wants to use MySQL for the database. Even worse is that he's the one deciding, since I started working there just a couple of weeks ago.

Now, I really, really want to use Mongodb. It integrates so wonderfully with Node together with Mongoose, and just the thought of using JSON everywhere makes my body shiver of satisfaction.

So therefore I have two questions.

A. Would you prefer Mongodb over MySQL for a node application?
B. How the hell can I convince him to use Mongodb?!

Cheers!

Why is it that in my IT class, peoplle think it is a great idea to say they know how to use mySQL to create databases and then end up destroying the CentOS VPS they had installed for them... like if you really are that retarded, use Microsoft Access, or better yet, LEARN FUCKING MYSQL BEFORE USING IT

"Configuring incomplete, errors occurred!" Ok, I get that. But would it kill you to tell me what errors? If you behave like an asshole, I'll hate you as well!

I want to cry... Fuck it.. shiit. .. :( :( ;(

Wasted half of the Weekend to Setup MySQL on my vServer which uses ssl encryption, have specific User and so on.
Thought: well, the User mysql is not so good as a Name. Drop it, you don't need it.
What did I? Instead of Drop User mysql , I typed Drop Database mysql.

Fuck that fucking Shit. I'm so sad right now. Broked the complete MySQL Database. Nothing is working anymore. And the server is new, I've Just made One Backup. Deleted this a few hours ago.. also accidently.

Help me :( Shit :( so sad :( Now, I don't have Motivation anymore to work with the vServer :(

Why the actual fuck is MariaDB disguised as MySQL in the AUR?!? Is there just no way to install MySQL from the AUR anymore?

The client has been working with MySQL his whole life, wants me to make a front end for a site but insists on making what he calls the backend in my terms the database himself. So he wants the ability to drop and add rows, tables from the database itself somehow implemented, any ideas?

My fascination for programming began around 13, when i started developing plugins for my minecraft server in java.
Had an awesome time with creating plugins for some fully custom servers with relatively large playerbases(50-200 players, depended on the time of the day).
This sparked something in me, and i started creating crapp ass "portfolio" sites for myself with php and mysql login and registration forms. After that I got into some basic c# abd had fun with some cute console/form applications.
And here comes today, in the process of picking up more css, php, html, js knowledge, probably heading towards react or vue.
I just love programming to death.

Today, i learned that $dql != $sql, crying

Me and some friends are working on creating a food recipe app and webapp. Currently in Norwegian, but would it be worth the trouble of translating all content and the app itself?

Backend written in PHP/MySQL with Laravel and app written with Ionic Framework v1.

I remember back then when we were building an E-commerce website. To maintain good performance the boss insisted using flat table. This was also applied to other projects like GPS. That was already 2013 when NoSQL databases like MongoDB was around already. His concern is he didn't like to risk on new technologies and it would cost money for training instead of using the existing "MySQL" and Microsoft SQL Server.
Everything I learned from that guy was just poop.

Convinced someone to start using ubuntu. Now we spent 25 mins getting mySQL and workbench to work. He was getting pretty frustrated, but then we got it working and he was so happy about it.

Now he knows.
No turning back.

URG!

I cannot think about a title, so just story:
in my position as multi headed chimera one of my ongoing task is it to dedust old excel sheets, processes and other super inefficient relics that steal time. Mostly i solve those with some tiny vba scripts, bigger vba scripts or a tiny java applications. usually that takes a few hours or maybe two days, depending on what i think is necessary.

the current task at hand is for our (physical) production, work time is noted on a sheet of paper and later given to the production head. Who then proceeds to type it all in excel to do his thing. The guy is starved of time by a huuge margin.

So, crafty kangaroo that i am i think: a barcode scanner, some raspberry pis with touchscreens and some mediocre php/mysql/javascript will make our worries go away. of course this will be a longer task but there is no need to have it done immidiatly. So crafted a working prototype, presented it in the weekly company meeting and got it "greenlighted".

The other day our CEO-like guy was ranting that nothing in this company gets ever done and that people wasting their time with useless projects and named my project among them.

I dont get humans. First he gives thumbs up for this, knowing that it will probably take me 100 hours or so to create in a working manner but later he calls it "a waste of time?" I presented the use (reducing expensive mantime, paper waste and room for fudgery) and yet he calls it useless? (well, his point was that there are other problems (which are out of my reach anyway))

they guy normally is pretty nice and has an ear for problems, but when it comes to higher computer stuff (>excel) he really struggles.

:/

i really like my side project, gives me room to flex some muscles and test stuff. Also playing with raspberry pis on worktime.

On a sidenote, anyone ever tried raspi mesh networks and knows where i get working >10 inch capacitive touch screens?

FUCK YOU EMOJIS! FUCK YOU AND YOUR EVER FUCKING GOD DAMN SPECIAL WAY OF BEING HANDLED.

Now that I have that part out...

I really fucking hate emoji at this time. Currently I'm working on one of my projects that has markdown support. One of the things I'm extendending the parser with is github style emoji (eg. :smile:) now this part works great. The problem however is getting that short code into a unicode char for HTML. And at the same time I have to take any unicode emoji inserted into the text box by phones and stuff and convert them into the shortcode (My database does support emoji but it's much nicer to store all emoji with the same standard)

All of this has taken 5 hours of research (needed a database of unicode -> short names) and several hours of converting the data from someone elses json into something I can use. (AKA Shrinking the damn file to only what I need) and now I've spent 5 more hours working on the actual code. And I still don't have it working properly.

So php7 deprecated all support for mysql none of my previous projects are working on localhost.Moreover,Ubuntu removed the php5 package from it's latest version . FML.

'"hi does that work

Another one of those success messages, that looks like an error message. feat. MySQL Workbench

So, let's version control MySQL. Any ideas?

Had trouble to connect to our MySQL database, so I decided to open a ticket to the Database admins. At least they are pros and I'm sure they'll help me:

"Hey guys, I have trouble connecting to [Hostname]. I guess it's a firewalling issue would you take a look? Attached are screenshots, saying hostname not found.

Answer:
Hey Dominique, are you sure the password you used is correct? Is it yours or the sysuser pw what you sent to the server? How did you send it?

Me: (kind of confused) Hey dear admin, did you look at my error message? It says Hostname not found. What do you think how I provided any credentials?

Support: yes, I saw your screenshot and don't see any password entry. That's why I asked!

Me: Well, than... ok... go and search for another job. Yeah and consider fucking yourself. Kisses.

Just succesfully setup database cluster , now I need balancer!

MySQL Server

I'm currently testing live and that includes trying sql injection, i have no backups. So if i forgot to escape string somewhere, I'm fucked. I like to live dangerous :D

Alos, i always test sql injection with "--; DROP ALL TABLES;" Casue... It's a bad idea..?

!rant

Today's progress. Updated the cms to update category titles :D So when you click the edit link, it displays the current category title in the input field. Then you just change the value and submit it to update the database info for that specific category. Fun stuff!

Stupidly tested some sql on development to return results for an admin (see the whole results) and stupidly didn't test the where clause for generic users (only see a subset of data)

To find out on production the where clause was being run because it wasn't a where, it was an 'and' and 'where' was not being used before so made the whole users get the entire results.

My own fault for not testing all use cases. Horrible though.
