TRUE and FALSE are the integers 1 and 0, respectively. ENUMs hold strings
which are assigned numbers starting with 1. That means that
WHERE enum_col = TRUE
will match rows whose enum_col has the *first* value defined in the ENUM list.
Also, every ENUM has the special error value '' in positio

Why don't you set enum('TRUE','FALSE')? I ask this because normally you
would query, when using NULL (all caps), WHERE Active IS NULL
I would suggest that if you want to compare against FALSE that you make
that one of your enumerated values. I would also make FALSE your default
value and the field not nullable. That way you don't have 3 possible
