好吧,我很困惑。我在尝试进行更新时收到“拒绝访问”错误。有一个授权允许该用户对该表执行更新,但无论如何它都被拒绝了。是的,我尝试过“刷新属性”。

桌子上有一个触发器:
CREATE TRIGGER DEFINER=`DEFINER`@`localhost` UserPasswordUpdate BEFORE UPDATE ON User
FOR EACH ROW
BEGIN
DECLARE count int;
IF(NOT NEW.Password<=>OLD.Password) THEN
SELECT count(*) into count FROM UserOldPassword WHERE UserID=NEW.UserID AND Password=NEW.Password;
IF(count != 0) THEN
INSERT INTO Unknown VALUES(1);
END IF;
INSERT INTO UserOldPassword(UserID,PasswordDate,Password) VALUES(NEW.UserID, NOW(), NEW.Password);
SET NEW.LastPasswordChangeDate=NOW();
END IF;
END
执行用户(见上文)和声明的定义者都应该有权插入到 UserOldPassword 表中:
