Question

我想在MYSQL数据库上创建事件。当我运行创建EVENT SCHEDULE的查询时出现此错误：

1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 8

有线的是，当我在EVENT SCHEDULE中运行查询时，它运行正常而没有任何错误：

这是我正在使用的代码

CREATE DEFINER=`root`@`localhost` EVENT `updateGoals` ON SCHEDULE EVERY 20 MINUTE STARTS '2015-01-01 00:01:00' ON COMPLETION NOT PRESERVE ENABLE DO BEGIN

UPDATE `scores` SET `goals`='0'
WHERE `goals` >'0'
AND
( `PROCESS_DESC` LIKE '%No Goals%'
OR `PROCESS_DESC` LIKE '%NG %'
OR `PROCESS_DESC` LIKE '%Goals 0%');

END$$

这就是你想要的。这个定界符是令人讨厌和令人困惑的。

DELIMITER $$
CREATE DEFINER=`root`@`localhost` 
       EVENT `updateGoals` 
          ON SCHEDULE EVERY 20 MINUTE 
      STARTS '2015-01-01 00:01:00' 
          ON COMPLETION NOT PRESERVE ENABLE
  DO BEGIN

    UPDATE `scores` SET `goals`='0'
     WHERE `goals` >'0'
      AND
           ( `PROCESS_DESC` LIKE '%No Goals%'
          OR `PROCESS_DESC` LIKE '%NG %'
          OR `PROCESS_DESC` LIKE '%Goals 0%');

END$$

你注意到你的活动只会运行一次，对吗？它说ON COMPLETION NOT PRESERVE。

如果您希望活动保持不变并继续按计划运行，直到DROP为止，请改为使用ON COMPLETION PRESERVE。

语法错误创建事件;查询工作正常
