Hi,
This is seemly simple, but I'm @ a loss this early in the morning. It's
best explained this way
SAMPLE
-----------------------------------
id | serial |
username | varchar(100)| constraint username >=8 and username <=100
The problem is that it's characters not integers or numeric. It my
constraint correct?
Thanks for the help,
J

Perhaps you mean "length(username) >= 8" and so on?
