How to create a unique constraint on a varchar(max) field in visual studio, visually.
the problem is when i try it:
manage indexes and keys > add > columns
I can only chose the bigint columns, but not any of the varchar(max) ones.
Do I maybe have to use check constraints?
If yes, what to put in the expression?
Thnx for the info
