    <p>I am using the following query to obtain some sales figures. The problem is that it is returning the wrong data.</p> <p>I am joining together three tables <code>tbl_orders</code> <code>tbl_orderitems</code> <code>tbl_payment</code>. The <code>tbl_orders</code> table holds summary information, the <code>tbl_orderitems</code> holds the items ordered and the <code>tbl_payment</code> table holds payment information regarding the order. Multiple payments can be placed against each order.</p> <p>I am trying to get the sum of the items <code>sum(mon_orditems_pprice)</code>, and also the amount of items sold <code>count(uid_orderitems)</code>. </p> <p>When I run the following query against a specific order number, which I know has 1 order item. It returns a count of 2 and the sum of two items.</p> <pre><code>Item ProdTotal ProdCount Westvale Climbing Frame 1198 2 </code></pre> <p>This order has two payment records held in the <code>tbl_payment</code> table, which is causing the double count. If I remove the payment table join it reports the correct figures, or if I select an order which has a single payment it works as well. Am I missing something, I am tired!!??</p> <pre><code>SELECT txt_orditems_pname, SUM(mon_orditems_pprice) AS prodTotal, COUNT(uid_orderitems) AS prodCount FROM dbo.tbl_orders INNER JOIN dbo.tbl_orderitems ON (dbo.tbl_orders.uid_orders = dbo.tbl_orderitems.uid_orditems_orderid) INNER JOIN dbo.tbl_payment ON (dbo.tbl_orders.uid_orders = dbo.tbl_payment.uid_pay_orderid) WHERE uid_orditems_orderid = 61571 GROUP BY dbo.tbl_orderitems.txt_orditems_pname ORDER BY dbo.tbl_orderitems.txt_orditems_pname </code></pre> <p>Any suggestions? </p> <p>Thank you.</p> <p>Drill down Table columns</p> <pre><code>dbo.tbl_payment.bit_pay_paid (1/0) Has this payment been paid, yes no dbo.tbl_orders.bit_order_archive (1/0) Is this order archived, yes no dbo.tbl_orders.uid_order_webid (integer) Web Shop's ID dbo.tbl_orders.bit_order_preorder (1/0) Is this a pre-order, yes no YEAR(dbo.tbl_orders.dte_order_stamp) (2012) Sales year dbo.tbl_orders.txt_order_status (varchar) Is the order dispatched, awaiting delivery dbo.tbl_orderitems.uid_orditems_pcatid (integer) Product category ID </code></pre>

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.
