# DROP TRIGGER

## Name

DROP TRIGGER -- remove a trigger

## Synopsis

    DROP TRIGGER name ON table

### Inputs

`name`

  The name of an existing trigger.

`table`

  The name of a table.

### Outputs

`DROP`

  The message returned if the trigger is successfully dropped.

`ERROR: DropTrigger: there is no trigger `name` on relation "`table`"`

  This message occurs if the trigger specified does not exist.

## Description

DROP TRIGGER will remove all references to an existing trigger definition. To execute this command the current user must be the owner of the table for which the trigger is defined.

## Examples

Destroy the `if_dist_exists` trigger on table `films`:

    DROP TRIGGER if_dist_exists ON films;

## Compatibility

SQL92

  There is no DROP TRIGGER statement in SQL92.

SQL99

  The DROP TRIGGER statement in PostgreSQL is incompatible with SQL99. In SQL99, trigger names are not local to tables, so the command is simply `DROP TRIGGER `name``.
