Very honestly, what's wrong here?

@linuxxx the result from the db should have been binary, true or false, 0 or 1. However it has now got entries for 'Y', 'N', '1' and '0'. Also since it's a char field any recklessness could result in any char being entered which would be evaluated as false which could have unexpected effects.
