### 26.3.45 The INFORMATION\_SCHEMA TRIGGERS Table

[]()

 The [`TRIGGERS`](information-schema-triggers-table.html) table provides information about triggers. To see information about a table's triggers, you must have the [`TRIGGER`](privileges-provided.html#priv_trigger) privilege for the table.

 The [`TRIGGERS`](information-schema-triggers-table.html) table has these columns:

* `TRIGGER_CATALOG`

   The name of the catalog to which the trigger belongs. This value is always `def`.

* `TRIGGER_SCHEMA`

   The name of the schema (database) to which the trigger belongs.

* `TRIGGER_NAME`

   The name of the trigger.

* `EVENT_MANIPULATION`

   The trigger event. This is the type of operation on the associated table for which the trigger activates. The value is `INSERT` (a row was inserted), `DELETE` (a row was deleted), or `UPDATE` (a row was modified).

* `EVENT_OBJECT_CATALOG`, `EVENT_OBJECT_SCHEMA`, and `EVENT_OBJECT_TABLE`

   As noted in [Section 25.3, “Using Triggers”](triggers.html), every trigger is associated with exactly one table. These columns indicate the catalog and schema (database) in which this table occurs, and the table name, respectively. The `EVENT_OBJECT_CATALOG` value is always `def`.

* `ACTION_ORDER`

   The ordinal position of the trigger's action within the list of triggers on the same table with the same `EVENT_MANIPULATION` and `ACTION_TIMING` values.

* `ACTION_CONDITION`

   This value is always `NULL`.

* `ACTION_STATEMENT`

   The trigger body; that is, the statement executed when the trigger activates. This text uses UTF-8 encoding.

* `ACTION_ORIENTATION`

   This value is always `ROW`.

* `ACTION_TIMING`

   Whether the trigger activates before or after the triggering event. The value is `BEFORE` or `AFTER`.

* `ACTION_REFERENCE_OLD_TABLE`

   This value is always `NULL`.

* `ACTION_REFERENCE_NEW_TABLE`

   This value is always `NULL`.

* `ACTION_REFERENCE_OLD_ROW` and `ACTION_REFERENCE_NEW_ROW`

   The old and new column identifiers, respectively. The `ACTION_REFERENCE_OLD_ROW` value is always `OLD` and the `ACTION_REFERENCE_NEW_ROW` value is always `NEW`.

* `CREATED`

   The date and time when the trigger was created. This is a `TIMESTAMP(2)` value (with a fractional part in hundredths of seconds) for triggers.

* `SQL_MODE`

   The SQL mode in effect when the trigger was created, and under which the trigger executes. For the permitted values, see [Section 5.1.11, “Server SQL Modes”](sql-mode.html).

* `DEFINER`

   The account named in the `DEFINER` clause (often the user who created the trigger), in `'*`user_name`*'@'*`host_name`*'` format.

* `CHARACTER_SET_CLIENT`

   The session value of the [`character_set_client`](server-system-variables.html#sysvar_character_set_client) system variable when the trigger was created.

* `COLLATION_CONNECTION`

   The session value of the [`collation_connection`](server-system-variables.html#sysvar_collation_connection) system variable when the trigger was created.

* `DATABASE_COLLATION`

   The collation of the database with which the trigger is associated.

#### Example

 The following example uses the `ins_sum` trigger defined in [Section 25.3, “Using Triggers”](triggers.html):

```
mysql> SELECT * FROM INFORMATION_SCHEMA.TRIGGERS
       WHERE TRIGGER_SCHEMA='test' AND TRIGGER_NAME='ins_sum'\G
*************************** 1. row ***************************
           TRIGGER_CATALOG: def
            TRIGGER_SCHEMA: test
              TRIGGER_NAME: ins_sum
        EVENT_MANIPULATION: INSERT
      EVENT_OBJECT_CATALOG: def
       EVENT_OBJECT_SCHEMA: test
        EVENT_OBJECT_TABLE: account
              ACTION_ORDER: 1
          ACTION_CONDITION: NULL
          ACTION_STATEMENT: SET @sum = @sum + NEW.amount
        ACTION_ORIENTATION: ROW
             ACTION_TIMING: BEFORE
ACTION_REFERENCE_OLD_TABLE: NULL
ACTION_REFERENCE_NEW_TABLE: NULL
  ACTION_REFERENCE_OLD_ROW: OLD
  ACTION_REFERENCE_NEW_ROW: NEW
                   CREATED: 2018-08-08 10:10:12.61
                  SQL_MODE: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,
                            NO_ZERO_IN_DATE,NO_ZERO_DATE,
                            ERROR_FOR_DIVISION_BY_ZERO,
                            NO_ENGINE_SUBSTITUTION
                   DEFINER: me@localhost
      CHARACTER_SET_CLIENT: utf8mb4
      COLLATION_CONNECTION: utf8mb4_0900_ai_ci
        DATABASE_COLLATION: utf8mb4_0900_ai_ci
```

 Trigger information is also available from the [`SHOW TRIGGERS`](show-triggers.html) statement. See [Section 13.7.7.40, “SHOW TRIGGERS Statement”](show-triggers.html).
