DROP TRIGGER(7)                                           SQL Commands                                           DROP TRIGGER(7)



NAME
       DROP TRIGGER - remove a trigger


SYNOPSIS
       DROP TRIGGER [ IF EXISTS ] name ON table [ CASCADE | RESTRICT ]


DESCRIPTION
       DROP  TRIGGER  removes an existing trigger definition. To execute this command, the current user must be the owner of the
       table for which the trigger is defined.

PARAMETERS
       IF EXISTS
              Do not throw an error if the trigger does not exist. A notice is issued in this case.

       name   The name of the trigger to remove.

       table  The name (optionally schema-qualified) of the table for which the trigger is defined.

       CASCADE
              Automatically drop objects that depend on the trigger.

       RESTRICT
              Refuse to drop the trigger if any objects depend on it. This is the default.

EXAMPLES
       Destroy the trigger if_dist_exists on the table films:

       DROP TRIGGER if_dist_exists ON films;


COMPATIBILITY
       The DROP TRIGGER statement in PostgreSQL is incompatible with the SQL standard. In the SQL standard,  trigger  names  are
       not local to tables, so the command is simply DROP TRIGGER name.

SEE ALSO
