Hi Experts, I need a trigger to update table tScheduleRequests when an INSERT is performed on table AR1.  This is actually my first attempt at a trigger and I know it's not too difficult, but I need a push in the right direction... This is what I have so far using the SQL template as a guide:

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE TRIGGER trUpdateScheduleRequestsA1
   ON  dbo.AR1
   AFTER INSERT
AS

IF EXISTS (SELECT OrderNumber, SchDte FROM Schedule.dbo.tScheduleRequests, inserted WHERE OrderNumber=Ordno)

BEGIN

	SET NOCOUNT ON;

	UPDATE Schedule.dbo.tScheduleRequests
	SET ScheduledDate=i.SchDte
	INNER JOIN inserted As i
		ON tScheduleRequests.OrderNumber=i.Ordno

END
GO

Open in new window


Thanks in advance

-Jeremy

You're welcome.

The INNER JOIN automatically prevents unwanted rows from being UPDATEd.
