In my TSQL table I added a constraint with the following sQL statement
alter table disabledqualities
add constraint uc_uIdQualCode
unique (userId, qualitycode)
I did it by hand because I just can't work out how the GUI is supposed to work.
You add a constraint and then you get a window where you should "define" your constraint. It's basically just a textbox. And no matter what I seem to enter, it never validates..
What am I supposed to enter in the box?
