我试图在Adminer 上创建一个MYSQL 触发器,但它不起作用。这是我的代码:
CREATE TRIGGER handle100kRows BEFORE INSERT ON `4013834123456`
FOR EACH ROW
BEGIN
IF (SELECT COUNT(*) FROM `4013834123456`) = "100000" THEN BEGIN
DELETE FROM 4013834123456 ORDER BY id LIMIT 1
END
END IF
END;
出现以下错误:(1064):(1064):第6行'4013834123456 ORDER BY id LIMIT 1 END END IF END'附近的语法错误
我刚刚尝试过;在 END 上,但随后出现更多错误...我使用 Adminer 4.1.0 和 MySQL 数据库!谢谢帮助!
更新,现在可以使用分隔符:
delimiter |
CREATE TRIGGER handle100kRows BEFORE INSERT ON `4013834123456`
FOR EACH ROW
BEGIN
IF (SELECT COUNT(*) FROM `4013834123456`) = "100000" THEN
DELETE FROM `4013834123456` ORDER BY id LIMIT 1;
END IF;
END;
delimiter;
