如何添加觸發器以填充ModifiedDate

Question

是否有可能在更新/更改行時使ModifiedDate自動更新CurrentDateTime？

SELECT [ID] 
     ,[PK] 
     ,[Iteration] 
     ,[Exam01] 
     ,[Exam02] 
     ,[Exam03] 
     ,[Exam04] 
     ,[Exam05] 
     ,[Exam06] 
     ,[Exam07] 
     ,[Exam08] 
     ,[Exam09] 
     ,[Exam10] 
     ,[Exam11] 
     ,[Exam12] 
     ,[Exam13] 
     ,[Exam14] 
     ,[HRGCode] 
     ,[AgeStart] 
     ,[AgeEnd] 
     ,[CreateDate] 
     ,[ModifiedDate] --- Need this to update when the row is Modified! 
     ,[ModifiedBy] 
     ,[Comments] 
    FROM [CommDB].[dbo].[tblRadiologyNucMedLookup] c 
    order by ID 

Answer 1

你真的需要觸發器嗎？您可以在同一個UPDATE聲明中使用該列，如

update tblRadiologyNucMedLookup 
set Iteration = 10, 
[ModifiedDate] = getdate() 
where ID = 101;
