DROP TRIGGER

This MySQL statement deletes a trigger.

Syntax

Below is the syntax for this command. Text within square brackets (i.e, [ and ] ) are optional. Choices are separated by bars (i.e, | ). Ellipses preceded by a comma indicates a repeating pattern. Ellipses before or after syntax are used to highlight a relevant except from the larger syntax. Text displayed in italic letters represent text that should be replaced with the specific names related to the database (e.g., column with the name of the column).

DROP TRIGGER [IF EXISTS] [database.]trigger

Explanation

This statement deletes a trigger. The IF EXISTS keyword prevents error messages when the trigger doesn't exist. Instead, a note will be generated, which can be displayed afterwards by executing the SHOW WARNINGS statement. You may specify the database or schema with which the trigger is associated. If not given, the current default database is assumed. As of version 5.1.6 of MySQL, this statement requires the TRIGGER privilege for the table related to the trigger given. Previously it required SUPER privilege. When upgrading from version 5.0.10 or earlier of MySQL, be sure to drop all triggers because there's a problem with using or dropping triggers from earlier versions.
