Facing problem in parameters of the Query

Question

Hi All,
I made 1 query through query generation ..... The Query withput parameters is working fine but when i have applied selection criteria's like Date wise,Item Wise,Document wise,sales employee wise it is getting executed only when all the parameters are put but it should actually work in either or & also end condition & also wiithout parameters .the query which i tried is given below:---
*SELECT T1.[ItemCode], T0.[DocDate], T0.[CardName], T0.[DocNum], T1.[U_BARCODE], T1.[U_Pu], T1.[U_Pcs], T1.[U_GRWT], T1.[Quantity],T0.[DocTotal], T2.[SlpName] FROM [dbo].[OINV]  T0 INNER JOIN [dbo].[INV1]  T1 ON T0.DocEntry = T1.DocEntry INNER JOIN OSLP T2 ON T0.SlpCode = T2.SlpCode, CRD1 T3 WHERE ((T0.DocDate >= '[%0]' and T0.DocDate <= '[%1]') or ('[%0]' = '' and '[%1]' = '')) and (T0.CardName= '[%6]' or '[%6]' = '') AND  (T1.ItemCode ='[%2]' or '[%2]' = '') and ((T0.DocNum >= '[%3]' and T0.DocNum <= '[%4]') or ('[%3]' = '' and '[%4]' = '')) and (T1.[u_BARCODE]='[%5]' or '[%5]' = '') AND  ( T2.[SlpName] ='[%7]' or '[%7]' = '') and  (  T3.[City] ='[%8]' or '[%8]' = '')*

hai!
declare @fromDate Datetime
declare @todate datetime
set @fromDate = (select min(s0.DocDate) from OINV s0 where s0.Docdate >='[%0]')
set @todate = (select max(s1.docdate) from OINV s1 where s1.Docdate <='[%1]')
SELECT T1.ItemCode, T0.DocDate, T0.CardName, T0.DocNum, T1.U_BARCODE, T1.U_Pu, T1.U_Pcs, T1.U_GRWT, T1.Quantity,T0.DocTotal, T2.SlpName FROM dbo.OINV T0 INNER JOIN dbo.INV1 T1 ON T0.DocEntry = T1.DocEntry INNER JOIN OSLP T2 ON T0.SlpCode = T2.SlpCode, CRD1 T3 WHERE ((T0.DocDate >= @fromdate and T0.DocDate <= @todate) ) and (T0.CardName= '%6' or '%6' = '') AND (T1.ItemCode ='%2' or '%2' = '') and ((T0.DocNum >= '%3' and T0.DocNum <= '%4') or ('%3' = '' and '%4' = '')) and (T1.u_BARCODE='%5' or '%5' = '') AND ( T2.SlpName ='%7' or '%7' = '') and ( T3.City ='%8' or '%8' = '')
if other selection not working fine, then extend the first four lines to all selections..
