属性值

A Boolean value that specifies whether the index ignores duplicate keys. If True, the index ignores duplicate keys. If False (default), the index includes rows with duplicate keys.

备注

This property controls error generation when an INSERT or UPDATE statement causes a constraint violation because there is a UNIQUE or PRIMARY KEY constraint implemented on the index.
