Thanks for the response, here is the query. In the query ReceiptRepository.NoTracking just gets System.Linq.IQueryable(of RECEIPT)
>From r In ReceiptRepository.NoTracking Where r.ID >= sReceipt And r.ID <= eReceipt Order By r.ID Select New SalesReceipt With { .Id = r.ID, .ReceiptDate = r.RECEIPTDATE, .Customer = If(r.RECEIPTCUSTOMERs.Any, r.RECEIPTCUSTOMERs.FirstOrDefault.CUSTOMER.PERSON.FULLNAME, String.Empty), .Cashier = r.SESSION.USER.USERNAME, .Cash = r.RECEIPTPAYMENTs.Where(Function(p) p.PAYMENTTYPE.TENDERTYPE = 1).Sum(Function(p) p.AMOUNT), .Card = r.RECEIPTPAYMENTs.Where(Function(p) p.PAYMENTTYPE.TENDERTYPE = 2).Sum(Function(p) p.AMOUNT), .Check = r.RECEIPTPAYMENTs.Where(Function(p) p.PAYMENTTYPE.TENDERTYPE = 3).Sum(Function(p) p.AMOUNT), .Others = r.RECEIPTPAYMENTs.Where(Function(p) p.PAYMENTTYPE.TENDERTYPE > 3).Sum(Function(p) p.AMOUNT), .Discount = r.RECEIPTLINEs.Sum(Function(l) l.RECEIPTDISCOUNTs.Sum(Function(d) d.DISCOUNT)), .SalesReturn = r.RECEIPTLINEs.Where(Function(l) l.QUANTITY < 0).Sum(Function(l) l.QUANTITY * l.PRICE - If(l.RECEIPTDISCOUNTs.Any, l.RECEIPTDISCOUNTs.Sum(Function(d) d.DISCOUNT), 0)), .Tax = r.RECEIPTLINEs.Where(Function(l) l.TAXABLE = True).Sum(Function(l) l.QUANTITY * l.PRICE - If(l.RECEIPTDISCOUNTs.Any, l.RECEIPTDISCOUNTs.Sum(Function(d) d.DISCOUNT), 0)), .Amount = r.RECEIPTPAYMENTs.Sum(Function(p) p.AMOUNT)}).ToList -----Original Message----- From: Jiri Cincura [mailto:disk...@cincura.net] Sent: Monday, April 30, 2012 1:34 AM To: For users and developers of the Firebird .NET providers Subject: Re: [Firebird-net-provider] Version 2.7.5.0 throwing Value Cannot be Null On Sat, Apr 28, 2012 at 10:41 PM, Muthu Annamalai <muthuannama...@sbcglobal.net> wrote: > some LINQ And what about providing that query? -- Jiri {x2} Cincura (x2develop.com founder) http://blog.cincura.net/ | http://www.ID3renamer.com ---------------------------------------------------------------------------- -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
