ALTER TABLE Processing Modifications

When an ALTER TABLE statement is processed for a table with any triggers with Event Times of either Before Update or After Update and a Column Dependency, these triggers are marked for Automatic Rebind by setting the Trigger Valid Indicator field of the Trigger DDD Member to N.

If an ALTER TABLE attempts to delete a Column on which a trigger depends, the ALTER fails with a DSF Return Code of TUC.
