Are you sure this kind of constraint is supported in MySQL 4.1?
I'm not saying they aren't, I just don't remember. Unless you're sure they
are, you should check the manual.

Hi, I need to do a constraint that checks if the field 'salary' of one
table is not smaller than zero. Like:
create table employee (
name varchar(30),
salary numeric(10,2)
constraint ck_salary check (salary > 0)
);
What´s the sintaxe? I'am not finding the correct sintaxe to do this
constraint.
I'm using MySQL 4.1
