Purpose

Drops the definition for the specified trigger from its subject table.

When you drop a trigger, the system:
  • Sets an EXCLUSIVE lock on the trigger.
  • Frees the disk space used by the dropped trigger and any fallback copy.
  • Removes any explicit access privileges on the object.
  • Removes the metadata for the dropped object from the data dictionary.

Required Privileges

To drop a trigger, you must have DROP TRIGGER privilege on either the subject table of the trigger, or the database containing that table.
