    <p>I have three tables in an SQL 2005 database, that I need to query and display on one row. The tables are:</p> <pre><code>MasterStock StockID, Description 1, Plate 2, Bowl ShopStock ShopID, StockID, StockLevel 1,1,6 2,1,0 3,1,0 4,1,10 Sales StockId, ShopId, SoldQuantity, transDate 1, 1, 1, 5/1/2011 1,2,1, 5/1/2011 </code></pre> <p>I need to get them to show one row: </p> <p>StockID, Description, 1 Sales, 1 Stock, 2 Sales, 2 Stock, 3 Sales,…</p> <p>I have managed to get what somewhere with the query below:</p> <pre><code>SELECT MasterStock.StockID, MasterStock.Description, SUM(CASE WHEN sales.shopid = 1 THEN sales.Soldquantity ELSE 0 END) AS [1 Sold], MAX(CASE WHEN shopstock.shopid = 1 THEN shopstock.stockLevel ELSE 0 END) AS [1 Stock], SUM(CASE WHEN sales.shopid = 2 THEN sales.Soldquantity ELSE 0 END) AS [2 Sold], MAX(CASE WHEN shopstock.shopid = 2 THEN shopstock.stockLevel ELSE 0 END) AS [2 Stock], SUM(CASE WHEN sales.shopid = 3 THEN sales.Soldquantity ELSE 0 END) AS [3 Sold], MAX(CASE WHEN shopstock.shopid = 3 THEN shopstock.stockLevel ELSE 0 END) AS [3 Stock], SUM(CASE WHEN sales.shopid = 4 THEN sales.Soldquantity ELSE 0 END) AS [4 Sold], MAX(CASE WHEN shopstock.shopid = 4 THEN shopstock.stockLevel ELSE 0 END) AS [4 Stock] FROM ShopStock INNER JOIN Sales ON ShopStock.StockID = Sales.StockID AND ShopStock.shopID = Sales.ShopID INNER JOIN MasterStock ON ShopStock.StockID = MasterStock.StockID WHERE (sales.transdate &gt; 1/1/2010) GROUP BY MasterStock.StockID, MasterStock.Description </code></pre> <p>However, if there are no sales for the product it doesn’t show any stock levels. If I remove the shopID join on shopstock and sales it shows the stock levels, but reports inaccurate sales - multiplies by four (one for each shopstock record?).</p> <p>I know I’m missing something here, but I’m not getting anywhere! Any help would be greatly received.</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.
