WHOA THERE! The biggest misconception that people have with the @@identity global variable is that it will give you that last identity inserted for a particular table. It actually gives you the last identity inserted for ANY identity column in the database. In a high impact environment this could give you the wrong value, especially if you are using it in a trigger.
I STRONGLY recommend using the SCOPE_IDENTITY(), especially in triggers. This will give you the last value inserted into the table when using it in a trigger since it gives you the last identity value in the scope. Please check out the BOL for SQL Server and you will see a comparison between SCOPE_IDENTITY() and @@IDENTITY. -----Original Message----- From: Robert Bailey [mailto:[EMAIL PROTECTED] Sent: Monday, January 10, 2005 7:14 PM To: CF-Talk Subject: SQL Triggers A little rusty at the triggers I see, but here is what I got: CREATE TRIGGER dbo.MyTest ON dbo.UserTime AFTER INSERT AS DECLARE @UserTimeProjID Int , @OrderProjID Int, @InternalCostAdd Int,@ActualHours Int Select @UserTimeProjID, @OrderProjID, @InternalCostAdd,@ActualHours ( SELECT UT.ProjectID, Orders.ProjectID, UR.UserRate * UT.ActualHours , UT.ActualHours FROM Orders INNER JOIN UserTime UT ON Orders.OrderID = UT.OrderID INNER JOIN UserRates UR ON UT.UserID = UR.UserID AND UT.UserTimeID = @@IDENTITY ) UPDATE ProjectCosts SET InternalCost = ProjectCosts.InternalCost + @InternalCostAdd, ActualHours = ProjectCosts.ActualHours + @ActualHours WHERE ProjectID = @UserTimeProjID OR ProjectID = @OrderProjID go I am not sure if the @@identity works for the inserted row and if my select statement is correct. Any pointers?
