DROP TRIGGER(7)                  PostgreSQL 9.2.24 Documentation                  DROP TRIGGER(7)



NAME
       DROP_TRIGGER - remove a trigger

SYNOPSIS
       DROP TRIGGER [ IF EXISTS ] name ON table_name [ 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_name
           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
       CREATE TRIGGER (CREATE_TRIGGER(7))
