# DROP TRIGGER

## Name

DROP TRIGGER -- remove a trigger

## Synopsis

    DROP TRIGGER name ON table [ CASCADE | RESTRICT ]

## Description

`DROP TRIGGER` will remove 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

`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``.
