Unique Keys and Not Null Constraints


#1

DM (Ver 3.4.16.7) does not allow unique key columns to be nullable. What is the current status of this ‘rule?’ An older thread suggested making enforcement of the rule optional. I wholeheartedly agree. There are certainly situations where a nullable unique key is valid and is allowable in the DB.

Thanks.
