OK...You are exactly right...I have reorganized parantheses and problem solved...

Thank you very much..

Thank for your attention.

The original code is like this:

------------------------------------------------------------------------

SET QUOTED_IDENTIFIER ON

GO

SET ANSI_NULLS ON

GO

ALTER       PROC ml_goldEntrance2

 @FISNO int,

 @HESAP_NO int,

 @TARIH smalldatetime,

 @SATIRNO int,

 @STOK_KODU varchar(15),

 @STOK_KODU2 varchar(15),

 @GIRILEN_MIKTAR decimal(9),

 @GIRILEN_MILYEM int,

 @GIRILENISCILIK float

AS

BEGIN TRAN

INSERT INTO Islem_ana (fisno,hesap_no,tarih,satirno,islem_kodu,stok_kodu,stok_kodu2,miktar,tutar,hasborc)

  VALUES(@FISNO,@HESAP_NO,@TARIH,@SATIRNO,'AG',@STOK_KODU,@STOK_KODU2,@GIRILEN_MIKTAR,(@GIRILEN_MIKTAR*@GIRILENISCILIK)

UPDATE Islem_ana

set...

Thanks for your attentions...

I have solved the problem by using "\\" instead of "\"

I have also modified by connedtion string with all of your guidance as follows:

--------------------------------------------------------------------

public

...

Thanks for your reply.But When I put a semicolon then I will get the same error message:

-----------------------------------------------------------

public

static string connectionString...
