I would be grateful if you could help me to solve the problem.
I have scope_identity() that implemented in TRIGGER.

SQL

ALTER TRIGGER TempProcTrig
 ON Table_temp2 
  AFTER insert 
AS 
BEGIN  
      declare @TempIdentity int      
      set @TempIdentity =scope_identity()
      insert Table_Temp(TempID)
      values(@TempIdentity) 
END

When TRIGGER is fired @TempIdentity gets Identety column field, and set this value into another table.

But,allways after TRIGGER is fired @TempIdentity gets NULL.

Why TempIdentity dosen't get Identity field?What should i change in my code?

Thank you in advance.

Solution 1

scope_identity() function hold the recently added identity value.
You can not use it

but you can try this

SQL

ALTER TRIGGER TempProcTrig
 ON Table_temp2 
  AFTER insert 
AS 
BEGIN  
      insert Table_Temp(TempID)
      SELECT TempID FROM inserted
END

+5 This is my opinion too. And he should replace TempID with the identity field name of Table_temp2.
