Easiest way to make a column unique
What is the easiest way to make column unique?
I created a unique index on the field but I really dont need the index, so the overhead of the managing the index seems excessive. Is there any other way to make a column unique? Im thinking some sort of check constraint that does a select but I get an error every time I use a query in a check constraint.
Any ideas?
