    <p>I am really struggling with figuring out how to convert a MS Access CrossTab query into T-SQL to run on SQL2000 or into Linq-to-SQL. What I have is a query that looks like this in Access: </p> <p><img src="https://i.stack.imgur.com/b0Rhf.jpg" alt="Access Cross Tab Query"> And produces this: <img src="https://i.stack.imgur.com/hnUrt.jpg" alt="Access Cross Tab Query Results"></p> <p>The query basically groups by ItemID and StoreID and Sums the Qty sold, but with the CrossTab query in Access, I am able to have a unique ItemID for each row, a column for each StoreID, and the total Qty for each StoreID/ItemID combination as the value.</p> <p>How do you construct this in T-SQL 2000? I can build a simple select query with grouping, but it gives me the data in three columns, StoreID, ItemID, and Qty. But what I need is a column for ItemID and a column for every StoreID in the result set</p> <pre><code>SELECT Trans.TranSID as StoreID, TransDetail.TranItemID as ItemID, SUM(TransDetail.Qty) AS TotalQtyForStore FROM Trans INNER JOIN TransDetail ON Trans.TranID = TransDetail.TranID INNER JOIN Item ON TransDetail.TranItemID = Item.ItemID WHERE (Trans.TranDate &gt; CONVERT(DATETIME, '2005-01-01 00:00:00', 102)) AND (Trans.TranTypeID = 'so' OR Trans.TranTypeID = 'ca') AND (Trans.TranStatus &lt;&gt; 'v') AND (Item.ItemClassID = 'RHM') GROUP BY Trans.TranSID, TransDetail.TranItemID </code></pre> <p>Which produces this:</p> <p><img src="https://i.stack.imgur.com/q3SRM.jpg" alt="enter image description here"></p> <p>But what I really need to do is transform this data so that the StoreID values become columns, like the Access CrossTab query above.</p>

    1. COI wouldn't typically do this in the SQL, I'd perform the cross tab in whatever reporting tool I was using. It's relatively simple using reporting services for example.

    2. COI agree. It just drives me nuts that something like this takes 2 seconds in Access but I can't figure it out in T-SQL or Linq-to-SQL.

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.
