It doesn't work in SQL Server, that was the first thing I tried yesterday night when I saw this question. So, I agree with Dragan.

>In MySQL this syntax does not work. I usually refrain from creating boolean fields in the database and prefer single digit numeric values instead (0=false, 1 = true). In MySQL you cannot cast to bool (although the data type exists) and SQL Server boolean datatype does not exist.
