13.7.5.35 SHOW TRIGGERS Syntax

SHOW TRIGGERS [{FROM | IN} db_name]
    [LIKE 'pattern' | WHERE expr]

SHOW TRIGGERS lists the triggers currently defined for tables in a database (the default database unless a FROM clause is given). This statement returns results only if you have the SUPER privilege. It was implemented in MySQL 5.0.10. The LIKE clause, if present, indicates which table names to match (not trigger names) and causes the statement to display triggers for those tables. The WHERE clause can be given to select rows using more general conditions, as discussed in Section 19.18, “Extensions to SHOW Statements”.

For the trigger ins_sum as defined in Section 18.3, “Using Triggers”, the output of this statement is as shown here:

mysql> SHOW TRIGGERS LIKE 'acc%'\G
*************************** 1. row ***************************
  Trigger: ins_sum
    Event: INSERT
    Table: account
Statement: SET @sum = @sum + NEW.amount
   Timing: BEFORE
  Created: NULL
 sql_mode: 
  Definer: me@localhost

SHOW TRIGGERS output has the following columns:

You must have the SUPER privilege to execute SHOW TRIGGERS.

You can also obtain information about trigger objects from INFORMATION_SCHEMA, which contains a TRIGGERS table. See Section 19.15, “The INFORMATION_SCHEMA TRIGGERS Table”.
