DROP TRIGGER
Syntax
DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name
Contents
Description
This statement drops a trigger. The schema (database) name is optional. If the
schema is omitted, the trigger is dropped from the default schema.
Its use requires the TRIGGER
privilege for the table associated with the trigger.
Use IF EXISTS
to prevent an error from occurring for a
trigger that does not exist. A NOTE
is generated for a non-existent trigger
when using IF EXISTS
. See SHOW WARNINGS.
Note: Triggers for a table are also dropped if you drop the table.
Atomic DDL
MariaDB starting with 10.6.1
MariaDB 10.6.1 supports Atomic DDL and DROP TRIGGER
is atomic.
