The runtime behavior of DCL statements specified in SQL procedures depends on the session mode of the Teradata session in which the procedure is created.
  • A DCL statement specified within an explicit (user-defined) transaction in an SQL procedure in Teradata session mode must be the last statement in that transaction. Otherwise, the system raises a runtime exception.
  • When performing a procedure in ANSI session mode, each DCL statement specified in the procedure body must be followed by a COMMIT WORK request. Otherwise, the database aborts the request and raises a run time exception.
