The % in a LIKE clause, indicates that MySQL should have data BEFORE and AFTER $expression in the column before it will be returned. Because it's a TIME column, and the way in which you use $expression, it will either have only a % (additional data) before, or after $expression, or NOT AT ALL. So, the three options you have for this.... WHERE field LIKE '%$expression' / WHERE field LIKE '$expression%' / WHERE field='$expression' That's the only three options you have from what I see here... I've tested all of this just now, and they all work wonderfully.
