13.1.30 DROP TRIGGER Syntax

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 13.7.5.41, “SHOW WARNINGS Syntax”.

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

shell command line drop all triggers in one schemata:

mysql -B --column-names=FALSE -e "SELECT CONCAT('DROP TRIGGER ', TRIGGER_NAME, ';') FROM information_schema.TRIGGERS WHERE TRIGGER_SCHEMA = SCHEMA();" yourdatabase

will output the drop statements:

DROP TRIGGER my_table1_aft_ins;
DROP TRIGGER my_table1_aft_upt;
DROP TRIGGER my_table1_aft_delete;
DROP TRIGGER my_table2_aft_insert;
DROP TRIGGER my_table2_aft_update;

you can repipe it to mysql, or text file for editing, etc.
