I have two value in one table in database which I need to autoincrement. First value is ID it's a primary kay and it is setup as Identity Column and have (Is Identity) - Yes in properties. And how setup my second value (number) to autoincrement. When I setup his property (Is Identity) yes it automaticly change Identity Column for number.
Is possible to meke autoincrement for two value in one table in sql?
回答1:
It is not possible to have more than one identity column in a table (and I can't think of a valid reason for wanting to do so anyhow).
