DROP TRIGGER

drop-trigger-stmt:

DROP TRIGGER IF EXISTS schema-name . trigger-name

The DROP TRIGGER statement removes a trigger created by the CREATE TRIGGER statement. Once removed, the trigger definition is no longer present in the sqlite_schema (or sqlite_temp_schema) table and is not fired by any subsequent INSERT, UPDATE or DELETE statements.

Note that triggers are automatically dropped when the associated table is dropped.
