How are triggers managed in MySQL?
In MySQL 5.1, triggers can be created using the CREATE TRIGGER statement, and dropped using DROP TRIGGER. See Section 12.1.19, “CREATE TRIGGER Syntax”, and Section 12.1.30, “DROP TRIGGER Syntax”, for more about these statements. Information about triggers can be obtained by querying the INFORMATION_SCHEMA.TRIGGERS table. See Section 20.16, “The INFORMATION_SCHEMA TRIGGERS Table”.
