我正在尝试创建此触发器以防止插入空日期:
CREATE TRIGGER responses_before_insert BEFORE INSERT ON responses
FOR EACH ROW
BEGIN
IF (NEW.date_of_plan IS NULL OR NEW.date_of_plan = '0000-00-00') THEN
SET NEW.date_of_plan = CURDATE();
END IF;
IF (NEW.date_of_update IS NULL OR NEW.date_of_update = '0000-00-00') THEN
SET NEW.date_of_update = CURDATE();
END IF;
END
但是,我收到以下错误:
#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 5
任何人都可以解释什么是错的吗?
谢谢!

通过在查询之前更改分隔符来解决问题,即。我执行了
DELIMITER $$
在触发查询之前。

就像你一样,你需要一个分隔符。
DELIMITER $$
CREATE TRIGGER responses_before_insert BEFORE INSERT ON responses
FOR EACH ROW
BEGIN
IF (NEW.date_of_plan IS NULL OR NEW.date_of_plan = '0000-00-00') THEN
SET NEW.date_of_plan = CURDATE();
END IF;
IF (NEW.date_of_update IS NULL OR NEW.date_of_update = '0000-00-00') THEN
SET NEW.date_of_update = CURDATE();
END IF;
END $$
DELIMITER ;
然后您也可以将其设置为最后一行。更好的实践!
