Thank for last answer.. but new problem occur. I wrote this sp to call in Triggerr...
==========================
ALTER PROCEDURE usp_autoStamp2
@TableName nvarchar(128), --ª×è͵ÒÃÒ§·Õè¨Ðá¡é(ºÑ§¤Ñº)
@Key1 nvarchar(128) = NULL
AS
DECLARE @cSQL nvarchar(1000),
@cWhere1 nvarchar(1000)
IF @TableName IS NOT NULL
SET @cSQL =
'UPDATE ' + @Tablename +
' SET UserID = SYSTEM_USER, LastUpdate = GETDATE() FROM Inserted, ' + @TableName
ELSE
BEGIN
RAISERROR( ' ERROR! ', 16, 1)
RETURN 1
END
IF @Key1 IS NOT NULL
SET @cWhere1 = ' WHERE ' + @TableName +'.' + @Key1 +' = Inserted.' + @Key1
ELSE
BEGIN
Declare @Message nvarchar(100)
SET @Message = 'ERROR! no Key Column From '+ @TableName
RAISERROR( @Message, 16, 1)
END
Execute(@cSQL + @cWHERE1)
==========================
HERE is result.....
==========================
Server: Msg 208, Level 16, State 1, Line 1
Invalid object name 'Inserted'.

Why I can't call Inserted table from SP inside Trigger!!
As I very sure abut syntax as thlis statement...
UPDATE Item SET UserID = SYSTEM_USER, LastUpdate = GETDATE() FROM Inserted, Item WHERE Item.ID = Inserted.ID
If there're no way to reference to Inserted table outer Trigger. How could we use it?
