New version, different problem:

CREATE TRIGGER TR_TRANSACTION_INSERT ON [dbo].[Transaction]
INSTEAD OF INSERT
AS

BEGIN

Declare @Quart int, @DhCreation datetime

SET @DhCreation = inserted.DhCreation
SET @Quart = dbo.GetQuartID(@DhCreation)


INSERT INTO [Transaction] (DhCreation, QuartID) values (@DhCreation,@Quart)

END



=================


I get:

The column prefix "inserted" does not match with a table or alias name used in the query...

I tought that inserted, updated, deleted was referring to the table being inserted, deleted, or updated to ????
