ALTER TRIGGER trigger_name ON table_name

RENAME TO new_name;

?

ALTER TRIGGER last_name_changes ON employees

RENAME TO log_last_name_changes;

?

ALTER TABLE table_name

DISABLE TRIGGER trigger_name | ALL

You specify the trigger name after the?DISABLE TRIGGER?clause to disable a particular trigger. To disable all triggers associated with a table, you use?ALL?instead of a particular trigger name.

DROP TRIGGER [IF EXISTS] trigger_name ON table_name;
