Question

I wrote one stored procedure.
My requirement is i have to show the data like if any No column has different Account_Names i have to show like Account_Name :Multipul(varchar))
Create PROCEDURE [dbo].[OpenVendorBIllsSP] (#FromDate Date,#ToDate Date)
AS
BEGIN
select
ROW_NUMBER() OVER(Order by vendor.VendorName ) AS ID,
PH.PurchasingHeaderID as No,
PH.TotalPriceCompanyCurrency as Balance,
acc.AccountName as [Account_Name],
PD.LineMemo as Memo,
from PurchasingHeader PH
LEFT OUTER JOIN TransactionType Trans ON PH.TransactionTypeID =Trans.TransactionTypeID
LEFT OUTER JOIN Vendor vendor on PH.VendorID=vendor.VendorID
LEFT OUTER JOIN PaymentTerm PT on PT.PaymentTermID = vendor.PaymentTermID
LEFT OUTER JOIN PurchasingDetail PD on PD.PurchasingHeaderID = PH.PurchasingHeaderID
LEFT OUTER JOIN Account Acc on Acc.AccountID= PD.FinancialAccountID
where PH.TransactionTypeID=7
Group by vendor.VendorName,
PH.PurchasingHeaderID,PH.TotalPriceCompanyCurrency,acc.AccountName
END
GO

LEFT OUTER JOIN Vendor vendor on PH.VendorID=vendor.VendorID
LEFT OUTER JOIN PaymentTerm PT on PT.PaymentTermID = vendor.PaymentTermID
LEFT OUTER JOIN PurchasingDetail PD on PD.PurchasingHeaderID = PH.PurchasingHeaderID
LEFT OUTER JOIN Account Acc on Acc.AccountID= PD.FinancialAccountID
where PH.TransactionTypeID=7
Group by vendor.VendorName,PH.PurchasingHeaderID ,
PH.PurchasingHeaderID,PH.TotalPriceCompanyCurrency,acc.AccountName

Answer 1

You could do a subsection that has everything, then GROUP BY acc.AccountName, PH.TotalPriceCompanyCurrency, etc and do a CASE WHERE COUNT(acc.AccountName) > 1
