我正在使用Trigger将Products表更新为当前日期,如果该列的值为null.我还有一切,当我将新值插入表中时,DateAdded列为NULL而不是今天的当前日期.我不确定什么是错的,为什么它不起作用.任何帮助将不胜感激,谢谢!
IF OBJECT_ID('Products_INSERT') IS NOT NULL
DROP TRIGGER Products_INSERT
CREATE TRIGGER Products_INSERT
ON Products
AFTER INSERT
AS
UPDATE Products
SET DateAdded = GETDATE()
WHERE DateAdded = NULL;
