MySQL查看事件

创建好事件后，用户可以通过以下 3 种方式来查看事件的状态信息：

1. 查看 mysql.event
2. 查看 information_schema.events
3. 切换到相应的数据库后执行 SHOW EVENTS;

以上方式的运行结果基本一致，这里就不一一演示了。下面查看 information_schema.events 表中的事件状态信息。SQL 语句和运行结果如下：

mysql> SELECT * FROM information_schema.events limit 1\G
*************************** 1. row ***************************
       EVENT_CATALOG: def
        EVENT_SCHEMA: test
          EVENT_NAME: e_test
             DEFINER: root@localhost
           TIME_ZONE: SYSTEM
          EVENT_BODY: SQL
    EVENT_DEFINITION: INSERT INTO tb_eventtest(user,createtime)VALUES('MySQL',NOW())
          EVENT_TYPE: RECURRING
          EXECUTE_AT: NULL
      INTERVAL_VALUE: 5
      INTERVAL_FIELD: SECOND
            SQL_MODE: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
              STARTS: 2020-05-21 10:41:39
                ENDS: NULL
              STATUS: ENABLED
       ON_COMPLETION: PRESERVE
             CREATED: 2020-05-21 10:41:39
        LAST_ALTERED: 2020-05-21 10:41:39
       LAST_EXECUTED: 2020-05-21 12:38:54
       EVENT_COMMENT:
          ORIGINATOR: 1
CHARACTER_SET_CLIENT: gbk
COLLATION_CONNECTION: gbk_chinese_ci
