Hi,
My name is Chinedu and I'm working as a Junior DBA in MTEL, Nigeria.
I'm trying to create a small database using MySQL but I'm
experiencing a problem which I belive could have been taken care of
with a NOT NULL constraint.
I created a table with MySQL (INNODB) and a form using PHP to insert
values into the underlying table.
I set some columns in the table to NOT NULL but I noticed that when I
left those NOT NULL fields blank, the insert operation still worked;
thereby inserting empty strings in the NOT NULL columns.
Please, how do I make my table reject those empty strings at the
database and form level? I would be glad if you can help me out with
this bug.
Chinedu.
