SQL Server unique contraint problem
- by b0x0rz
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
