Re: [phpMyAdmin Developers] Add support for CHECK constraints

Since mysql does not provide an option to edit a check constraint or even
to describe it, I was thinking about making that functionality myself.
Check constraints will be saved in a table named pma_checkConstraints in
phpmyadmin databse, where we will store all the info about ccs. This way,
we can also add an option to edit a cc.
I'll also create a new class CheckConstraint which will handle all the
functionality.
Any suggestions??
