MYSQL - 創建事件刪除過期的記錄

Question

我對MySQL事件驗證碼：

CREATE EVENT DeleteToken 
ON SCHEDULE EVERY 1 MINUTE 
DO 
BEGIN 
DELETE FROM 
`password_recovery` 
WHERE `date_expires` < 
CURRENT_TIMESTAMP(); 
END 

當我運行它，我得到以下錯誤：

#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 

date_exires是datetime與格式YYYY-MM-DD HH:MM:SS CURRENT_TIMESTAMP()有什麼問題。

我也試過CURRENT_TIMESTAMP但它給了我同樣的錯誤。

Answer 1

我建議你使用這個查詢 -

CREATE EVENT DeleteToken 
ON SCHEDULE EVERY 1 MINUTE 
DO 
DELETE FROM `password_recovery` WHERE `date_expires` < CURRENT_TIMESTAMP(); 

否則，當你使用BEGIN..END條款，你應該使用DELIMITER命令 -

DELIMITER $$ 
CREATE EVENT DeleteToken 
ON SCHEDULE EVERY 1 MINUTE 
DO 
BEGIN 
    DELETE 
    FROM `password_recovery` 
    WHERE `date_expires` < CURRENT_TIMESTAMP(); 
END$$ 
DELIMITER ; 

Answer 2

只需使用Now()代替CURRENT_TIMESTAMP()

Answer 3

代替

ON SCHEDULE EVERY 1 MINUTE 

嘗試

ON SCHEDULE 1 MINUTE 

完全schecule西港島線是這樣的：

CREATE EVENT DeleteToken 
ON SCHEDULE 1 MINUTE 
DO 
    BEGIN 
    DELETE FROM `password_recovery` WHERE `date_expires` < CURRENT_TIMESTAMP(); 
    END 

Answer 4

你需要設置分隔符在查詢：

DELIMITER | 

CREATE EVENT 
... 
CURRENT_TIMESTAMP(); 
END| 

DELIMITER ; 

如果使用phpMyAdmin，請設置分隔符字段而不是手動設置分隔符。

Answer 5

使用DELIMITER

DELIMITER $$ 
CREATE EVENT DeleteToken 
ON SCHEDULE EVERY 1 MINUTE 
DO 
BEGIN 
DELETE FROM 
`password_recovery` 
WHERE `date_expires` < 
Now(); 
END$$ 
DELIMITER ;
