GETUTCDATE（）返回null

Question

我在使用GETUTCDATE（）在表中插入更新字段后触发但在插入后我看到值= null

SET NOCOUNT ON 
UPDATE [dbo].[Employee] 
SET [CurrentDate] = GETUTCDATE() 
FROM inserted 
WHERE inserted.[Id] = [dbo].[Employee].[Id] 

Answer 1

尝试使用INNER JOIN语句并查看它是否有效，即

UPDATE [dbo].[Employee] 
SET [CurrentDate] = GETUTCDATE() 
FROM dbo.Employee 
INNER JOIN inserted  ON inserted.[Id] = [dbo].[Employee].[Id] 

...它可能不喜欢where子句
