在 phpMyAdmin 中创建事件时启动事务导致错误

Question

无论出于何种原因，phpMyAdmin 都不允许我使用“开始事务”创建事件。这是我正在使用的：

CREATE EVENT `set_history`
ON SCHEDULE
    EVERY 1 DAY STARTS '2018-9-29 00:00:00'
ON COMPLETION PRESERVE
DISABLE ON SLAVE
DO BEGIN

 START TRANSACTION;


INSERT INTO historical_transactions SELECT * FROM transactions WHERE domain IN (SELECT domain FROM domain JOIN accounts ON domain.accessAbility_ID = accounts.accessAbility_ID WHERE accounts.`renew_at` = DATE(NOW()));

DELETE FROM `transactions` WHERE domain IN (SELECT domain FROM domain JOIN accounts ON domain.accessAbility_ID = accounts.accessAbility_ID WHERE accounts.`renew_at` = DATE(NOW()));

UPDATE `accounts` SET `renew_at`= DATE_ADD(DATE(NOW()), INTERVAL 1 MONTH) WHERE `renew_at` = DATE(NOW());

COMMIT;
END

当运行在事件之外时，START TRANSACTION、INSERT、DELETE、UPDATE 和 COMMIT 都有效。这是我不断收到的错误：

#1064 - 您的 SQL 语法有误；查看与您的 MySQL 服务器版本对应的手册，了解在第 8 行

附近使用的正确语法

希望能帮到你。谢谢。

Answer 1

您需要将 DELIMITER 定义为除 (;) 以外的其他内容（例如：$$），并在末尾将其重新定义回 (;)。

基本上，PHPMyAdmin 解析器会将 ; 解释为执行触发器，并且会尝试触发查询，而不是将其整体视为事件的 Create 语句。所以重新定义分隔符有助于绕过执行。

执行以下操作：

DELIMITER $$
CREATE EVENT `set_history`
ON SCHEDULE
    EVERY 1 DAY STARTS '2018-9-29 00:00:00'
ON COMPLETION PRESERVE
DISABLE ON SLAVE
DO BEGIN

 START TRANSACTION;


INSERT INTO historical_transactions SELECT * FROM transactions WHERE domain IN (SELECT domain FROM domain JOIN accounts ON domain.accessAbility_ID = accounts.accessAbility_ID WHERE accounts.`renew_at` = DATE(NOW()));

DELETE FROM `transactions` WHERE domain IN (SELECT domain FROM domain JOIN accounts ON domain.accessAbility_ID = accounts.accessAbility_ID WHERE accounts.`renew_at` = DATE(NOW()));

UPDATE `accounts` SET `renew_at`= DATE_ADD(DATE(NOW()), INTERVAL 1 MONTH) WHERE `renew_at` = DATE(NOW());

COMMIT;
END $$
DELIMITER ;
