    <p>I'm going to preface this question with the disclaimer that creating what I call "complex" queries isn't in my forte. Most of the time, there is a much simpler way to accomplish what I'm trying to accomplish so if the below query isn't up to par, I apologize.</p> <p>With that said, I have a table that keeps track of Vendor Invoices and Vendor Invoice Items (along with a Vendor Invoice Type and Vendor Invoice Item Type). Our bookkeeper wants a report that simply shows: Vendor | Location | Inv Number | Inv Type | Item Type | Inv Date | Rental Fee | Restock Fee | Shipping Fee | Line Item Cost | Total (Line Item + Fees)</p> <p>Most of the time, one vendor invoice is one line. However, there are exceptions where a vendor invoice can have many item types, thus creating two rows. Not a big deal EXCEPT the fees (Rental, Restock, Shipping) are attached to the Vendor Invoice table. So, I first created a query that checks the temp table for Invoices that have multiple rows, takes the last row, and zero's out the fees. So that only one line item would have the fee. However, our bookkeeper doesn't like that. Instead, she'd like the fees to be "distributed" among the line items. </p> <p>So, if a vendor invoice has a $25 shipping charge, has two line items, then each line item would be $12.50.</p> <p>After working with the query, I got it to update the Last Row to be the adjusted amount but row 1+ would have the original amount.</p> <p>I'm going to post my entire query here (again - I'm sorry that this may not be the best looking query; however, suggestions are always welcome)</p> <pre><code>DROP TABLE #tVendorInvoiceReport DROP TABLE #tSummary SELECT v.Name AS Vendor , vii.Location , vi.VendorInvNumber , vit.Descr AS InvoiceType , vii.VendorInvoiceItemType , CONVERT(VARCHAR(10), vi.VendorInvDate, 120) VendorInvDate , vi.RentalFee , vi.RestockFee , vi.ShippingFee , SUM(vii.TotalUnitCost) TotalItemCost , CONVERT(MONEY, 0) TotalInvoice , RowID = IDENTITY( INT,1,1) INTO #tVendorInvoiceReport FROM dbo.vVendorInvoiceItems AS vii JOIN dbo.VendorInvoices AS vi ON vii.VendorInvID = vi.VendorInvID JOIN dbo.Vendors AS v ON vi.VendorID = v.VendorID JOIN dbo.VendorInvoiceTypes AS vit ON vi.VendorInvTypeID = vit.VendorInvTypeID WHERE vi.VendorInvDate &gt;= '2012-01-01' AND vi.VendorInvDate &lt;= '2012-01-31' GROUP BY v.Name , vii.Location , vi.VendorInvNumber , vit.Descr , vii.VendorInvoiceItemType , CONVERT(VARCHAR(10), vi.VendorInvDate, 120) , vi.RentalFee , vi.RestockFee , vi.ShippingFee ORDER BY v.Name , vii.Location , vi.VendorInvNumber , vit.Descr , vii.VendorInvoiceItemType , CONVERT(VARCHAR(10), vi.VendorInvDate, 120) SELECT VendorInvNumber , COUNT(RowID) TotalLines , MAX(RowID) LastLine INTO #tSummary FROM #tVendorInvoiceReport GROUP BY VendorInvNumber WHILE ( SELECT COUNT(LastLine) FROM #tSummary AS ts WHERE TotalLines &gt; 1 ) &gt; 0 BEGIN DECLARE @LastLine INT DECLARE @NumItems INT SET @LastLine = ( SELECT MAX(LastLine) FROM #tSummary AS ts WHERE TotalLines &gt; 1 ) SET @NumItems = ( SELECT COUNT(VendorInvNumber) FROM #tVendorInvoiceReport WHERE VendorInvNumber IN ( SELECT VendorInvNumber FROM #tSummary WHERE LastLine = @LastLine ) ) UPDATE #tVendorInvoiceReport SET RentalFee = ( RentalFee / @NumItems ) , RestockFee = ( RestockFee / @NumItems ) , ShippingFee = ( ShippingFee / @NumItems ) WHERE RowID = @LastLine DELETE FROM #tSummary WHERE LastLine = @LastLine --PRINT @NumItems END UPDATE #tVendorInvoiceReport SET TotalInvoice = ( TotalItemCost + RentalFee + RestockFee + ShippingFee ) SELECT Vendor , Location , VendorInvNumber , InvoiceType , VendorInvoiceItemType , VendorInvDate , RentalFee , RestockFee , ShippingFee , TotalItemCost , TotalInvoice FROM #tVendorInvoiceReport AS tvir </code></pre> <p>I sincerely appreciate anyone who took the time to read this and attempt to point me in the right direction.</p> <p>Thank you, Andrew</p> <p>PS - I did try and remove "WHERE RowID = @LastLine" from the first Update, but that changed the Shipping Fees for the first line with two items to "0.0868" instead of 12.50 ($25/2)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
