Close to nothing, at least from what I have been able to find.
The MySQL docs don’t say much to persuade me otherwise. I found a great post here.
It claims the only purpose for the SIZE on an INT field is to determine how many ZEROs to pad with when using ZEROFILL.
So I ask, does anyone know if this is it? Is there more to it?
I can’t believe I didn’t run into this earlier.
I’ve never been a big fan of MySQL, for other reasons. But it seems to be pretty popular. Has to be more to it than just being FREE.
