5.23. PLVrb: Rollback Processing

The PLVrb (PL/Vision RollBack) package provides a programmatic interface to rollback activity in PL/SQL. See Chapter 20 for details.

FUNCTION rolling_back RETURN BOOLEAN;

Returns TRUE if rollback processing is being performed by PLVrbPLVcmt.

Returns TRUE if currently logging the fact that a rollback was performed by PLVrbPLVcmt.
