Not with a CHECK constraint as a that phrase is specific to a very specific object. But in many situations equivalent control can be achieved with a method: Something I have pointed to 4 or 5 times.

My issue here is not the name nor, yet again, am I claiming that Oracle has equivalent functionality ... I'm still just asking if there is something that can not be duplicated with an Oracle method. For example Oracle doesn't have IDENTITY columns but I can duplicate the functionality with a SEQUENCE.
