# ALTER TRIGGER

## Name

ALTER TRIGGER -- change the definition of a trigger

## Synopsis

    ALTER TRIGGER name ON table_name RENAME TO new_name

## Description

`ALTER TRIGGER` changes properties of an existing trigger. The `RENAME` clause changes the name of the given trigger without otherwise changing the trigger definition.

You must own the table on which the trigger acts to be allowed to change its properties.

## Parameters

`name`

  The name of an existing trigger to alter.

`table_name`

  The name of the table on which this trigger acts.

`new_name`

  The new name for the trigger.

## Notes

The ability to temporarily enable or disable a trigger is provided by ALTER TABLE, not by `ALTER TRIGGER`, because `ALTER TRIGGER` has no convenient way to express the option of enabling or disabling all of a table's triggers at once.

## Examples

To rename an existing trigger:

    ALTER TRIGGER emp_stamp ON emp RENAME TO emp_track_chgs;

## Compatibility

`ALTER TRIGGER` is a PostgreSQL extension of the SQL standard.
