  I have a table A and another B.I wanted to write a trigger so that if I insert or delete a row in table A it should also insert or delete that row in table B(with id) and also if update a row in table A it should also update the corresponding row in table B. all should be in one trigger.Can anyone help me in this issue.

  Thanks.

  Why the requirement to put everything in one trigger? Makes life complicated, I think...

  You can write a trigger on all three actions.

  
  
  CREATE TRIGGER tr_InsUpdDel ON tableA
  
  FOR INSERT, UPDATE, DELETE
  
  AS
  
  ...
  
  

  Inside the trigger you can check the count of the Inserted and Deleted tables :

  Deleted = 0, inserted <> 0 ==> INSERT

  Deleted = Inserted ==> UPDATE

  Deleted <> 0, inserted = 0 ==> DELETE
