13.7.7.7 SHOW CREATE EVENT Statement语句

SHOW CREATE EVENT event_name

This statement displays the CREATE EVENT statement needed to re-create a given event. 此语句显示重新创建给定事件所需的CREATE EVENT语句。It requires the EVENT privilege for the database from which the event is to be shown. 它需要显示EVENT的数据库的事件权限。For example (using the same event e_daily defined and then altered in Section 13.7.7.18, “SHOW EVENTS Statement”):例如(使用第13.7.7.18节,“SHOW EVENTS语句”中定义并更改的相同事件e_daily):

mysql> SHOW CREATE EVENT myschema.e_daily\G
*************************** 1. row ***************************
               Event: e_daily
            sql_mode: ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,
                      NO_ZERO_IN_DATE,NO_ZERO_DATE,
                      ERROR_FOR_DIVISION_BY_ZERO,
                      NO_ENGINE_SUBSTITUTION
           time_zone: SYSTEM
        Create Event: CREATE DEFINER=`jon`@`ghidora` EVENT `e_daily`
                        ON SCHEDULE EVERY 1 DAY
                        STARTS CURRENT_TIMESTAMP + INTERVAL 6 HOUR
                        ON COMPLETION NOT PRESERVE
                        ENABLE
                        COMMENT 'Saves total number of sessions then
                                clears the table each day'
                        DO BEGIN
                          INSERT INTO site_activity.totals (time, total)
                            SELECT CURRENT_TIMESTAMP, COUNT(*)
                              FROM site_activity.sessions;
                          DELETE FROM site_activity.sessions;
                        END
character_set_client: utf8mb4
collation_connection: utf8mb4_0900_ai_ci
  Database Collation: utf8mb4_0900_ai_ci

character_set_client is the session value of the character_set_client system variable when the event was created. 创建事件时character_set_client系统变量的会话值。collation_connection is the session value of the collation_connection system variable when the event was created. collation_connection是创建事件时collation_connection系统变量的会话值。Database Collation is the collation of the database with which the event is associated.Database Collation是与事件关联的数据库的排序规则。

The output reflects the current status of the event (ENABLE) rather than the status with which it was created.输出反映事件(ENABLE)的当前状态,而不是创建事件时的状态。
