Teradata Database does not support triggers created in Teradata Database 5.0 and earlier that specify any of the following no longer valid features:

  • INSTEAD OF as the trigger action time
  • BEFORE statement triggers
  • BEFORE row triggers with data-changing statements

Teradata Database reports an error if old triggers with any of these features are found by a triggering event on a table. Any such trigger must be redefined if it is to be used in the current release.
