DROP TRIGGER(7) PostgreSQL 15.7 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, and in turn
all objects that depend on those objects (see Section 5.14).
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.
