阻止 CREATE EVENT 的语法错误

Question

CREATE EVENT demo
    ON SCHEDULE
      EVERY 2 SECOND
    DO BEGIN

      update alarm set is_on=1;

    END

错误 SQL查询：

CREATE EVENT demo
    ON SCHEDULE
      EVERY 2 SECOND
    DO
      BEGIN
      update alarm set is_on=1;

MySQL 说：文档

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 6

Answer 1

当您运行这样的 DDL 语句时，您需要更改分隔符。 MySQL 将您的分号解释为 CREATE EVENT 查询的结尾，而不是其中的分隔符。

试试这个：

DELIMITER $$
CREATE EVENT demo
    ON SCHEDULE
      EVERY 2 SECOND
    DO BEGIN

      update alarm set is_on=1;

    END $$
DELIMITER ;
