OLD SQL Function

Previous Next

The OLD() SQL function is a USoft-specific extension of the SQL language. It is handled on all platforms by the USoft Rules Engine itself and thus portable across platforms.

This function must be passed exactly 1 argument, which must identify a column:

OLD( column )

This function is legal only in SQL contexts in Table Constraints and Domain Constraints.

For functionality, go to the " The OLD() Function " help topic.
