Session Mode Impact on DCL Statements in SQL Procedures

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, Teradata Database aborts the request and raises a run time exception.
