DROP TRIGGER
Removes a trigger.
Synopsis
DROP TRIGGER [IF EXISTS] <name> ON <table> [CASCADE | RESTRICT]
Description
DROP TRIGGER will remove an existing trigger definition. To run 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
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
Remove the trigger sendmail on table expenses;
DROP TRIGGER sendmail ON expenses;
Compatibility
The DROP TRIGGER statement in Apache Cloudberry 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.
