MySQL 8.0 Reference Manual  /  ...  /  DROP TRIGGER Statement

13.1.34 DROP TRIGGER Statement

DROP TRIGGER [IF EXISTS] [schema_name.]trigger_name

This statement drops a trigger. The schema (database) name is optional. If the schema is omitted, the trigger is dropped from the default schema. DROP TRIGGER 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 nonexistent trigger when using IF EXISTS. See Section 13.7.7.40, “SHOW WARNINGS Statement”.

Triggers for a table are also dropped if you drop the table.
