Question

CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
EVERY 1 DAY STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO CALL
sp_Notification();
SP_notificationStatus();

我想一个接一个地执行上面两个过程'sp_Notification'和'SP_notificationStatus'，但只执行'sp_Notification'过程。

如何使用一个事件执行2个程序？

Answer 1

我遇到了同样的问题，第二个程序被立即调用，这就是答案：

DELIMITER //                     -- THIS IS IMPORTANT!!!!
CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
  EVERY 1 DAY 
  STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO
BEGIN
  CALL sp_Notification();        -- Otherwise you event will end HERE after ;
  CALL SP_notificationStatus();
END;
END //                           -- Set delimiter back to ';'
DELIMITER ;

Answer 2

我想你想要这个：

CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
EVERY 1 DAY STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO CALL
sp_Notification();

CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
EVERY 1 DAY STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO CALL
SP_notificationStatus();

您也可以创建一个调用它们的新程序，然后安排一次。

Answer 3

您错过了CALL声明：

CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
EVERY 1 DAY STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO 
 BEGIN
  CALL sp_Notification();
  CALL SP_notificationStatus();
 END;

Answer 4

以下配置运行两个存储过程：

/*!50106 set global event_scheduler = 1*/;

/*Table structure for table `notification` */

DROP TABLE IF EXISTS `notification`;

CREATE TABLE `notification` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `mydate` DATETIME DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB;

/*Table structure for table `notificationStatus` */

DROP TABLE IF EXISTS `notificationStatus`;

CREATE TABLE `notificationStatus` (
  `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
  `mydate` DATETIME DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=INNODB;

/* Event structure for event `EVENT_NOTIFICATION` */

/*!50106 DROP EVENT IF EXISTS `EVENT_NOTIFICATION`*/;

DELIMITER $$

/*!50106 CREATE EVENT `EVENT_NOTIFICATION` ON SCHEDULE EVERY 5 SECOND
           STARTS '2013-10-12 00:00:00' ON COMPLETION NOT PRESERVE ENABLE
DO
BEGIN
    CALL `sp_Notification`();
    CALL `sp_notificationStatus`();
END */$$

DELIMITER ;

/* Procedure structure for procedure `sp_Notification` */

/*!50003 DROP PROCEDURE IF EXISTS  `sp_Notification` */;

DELIMITER $$

/*!50003 CREATE PROCEDURE `sp_Notification`()
BEGIN
    INSERT INTO `notification` (`mydate`) VALUES (NOW());
END */$$

DELIMITER ;

/* Procedure structure for procedure `sp_notificationStatus` */

/*!50003 DROP PROCEDURE IF EXISTS  `sp_notificationStatus` */;

DELIMITER $$

/*!50003 CREATE PROCEDURE `sp_notificationStatus`()
BEGIN
    INSERT INTO `notificationStatus` (`mydate`) VALUES (NOW());
END */$$

DELIMITER ;

Answer 5

DELIMITER //
创建活动EVENT_NOTIFICATION
安排时间表每一天开始＆＃39; 2013-10-15 15：42：00＆＃39;
评论＆＃39;插入通知＆＃39; DO
BEGIN
CALL sp_Notification（）;
CALL SP_notificationStatus（）;
结束//

Answer 6

我认为通过使用以下方法，您可以在一个事件中执行多个过程

DELIMITER $$

CREATE EVENT Raju_RemoveExpiredItemsEvent
ON SCHEDULE EVERY 1 DAY

DO
  BEGIN
        CALL Raju_DeleteExpiredItems('comments');
        CALL Raju_DeleteExpiredItems('likes');
        END$$

DELIMITER ;

Answer 7

当我遇到类似问题时，以上答案对我不起作用。

我通过创建一个新的存储过程来解决它，该存储过程包括事件中所需的过程。

示例

CREATE PROCEDURE `new_procedure` ()
BEGIN
   sp_Notification();
   SP_notificationStatus();
END

，并且在事件中

CREATE EVENT EVENT_NOTIFICATION
ON SCHEDULE
EVERY 1 DAY STARTS '2013-10-15 15:42:00'
COMMENT 'Insert Notification'
DO 
  CALL new_procedure();

使用一个事件执行两个过程
