Removes a trigger.

Synopsis

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

IF EXISTS
Do not throw an error if the trigger does not exist. A notice is issued in this case.

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

Examples

DROP TRIGGER sendmail ON expenses;

Compatibility

The DROP TRIGGER statement in Greenplum Database is not compatible with the SQL standard. In the SQL standard, trigger names are not local to tables, so the command is simply DROP TRIGGER name.
