      ,[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

你真的需要一个触发器吗？您可以在与

相同的UPDATE语句中添加该列

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