CREATE function fnDateRange
(@DateMin varchar(50), @datemax varchar(50))
returns table ( InvoiceTotal as numeric(12,4), InvoiceNumber as int, Invoicedate as date, Balance as numeric(12,4))

return
(SELECT InvoiceTotal, InvoiceNumber, InvoiceDate,InvoiceTotal - CreditTotal - PaymentTotal AS Balance
 FROM Invoices
 WHERE InvoiceDate BETWEEN @DateMin AND @DateMax)



select o.VENDORNAME, q.*
from vendors o
join dbo.fndaterange('april 10 2002', 'april 18 2002') AS Q
on o.VENDORID = Q.VENDORID
Hi tagtekin,

I think You should use  INNER JOIN between tour table and function.
But the problem here is i didn't dind any proper joining keye in your function. It's better to return one unique key, something like VendorId from your funcion and do a join

SELECT VendorName, t.*
FROM Vendors
INNER JOIN  dbo.fnDateRange (...) t
on t.VendorID = Vendors.vendorID

good point:

CREATE function fnDateRange
(@DateMin varchar(50), @datemax varchar(50))
returns table ( VendorIDas int , InvoiceTotal as numeric(12,4), InvoiceNumber as int, Invoicedate as date, Balance as numeric(12,4))

return
(SELECT Vendorid, InvoiceTotal, InvoiceNumber, InvoiceDate,InvoiceTotal - CreditTotal - PaymentTotal AS Balance
 FROM Invoices
 WHERE InvoiceDate BETWEEN @DateMin AND @DateMax)
CREATE function fnDateRange
(@DateMin varchar(50), @datemax varchar(50))
returns table ( VendorID as int , InvoiceTotal as numeric(12,4), InvoiceNumber as int, Invoicedate as date, Balance as numeric(12,4)) -- missed s space here

return
(SELECT Vendorid, InvoiceTotal, InvoiceNumber, InvoiceDate,InvoiceTotal - CreditTotal - PaymentTotal AS Balance
 FROM Invoices
 WHERE InvoiceDate BETWEEN @DateMin AND @DateMax)

ASKER

yes but this function created returns the vendor id directly from the function i needed to return that column from the select statement.

Thanks

are you getting any error ?
no I was getting since there was no vendorid coming from the function but i added andsolved the problem.
Ok.. now it seems that you are solved the problem
yes thank you very much
