    <p>I have this query, which works perfectly when I supply the retailer_id parameter with a value.</p> <pre><code>SELECT reda.RetailerId, ( SELECT SUM(reda.Purchases) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS Purchases, ( SELECT SUM(reda.PurchaseTotal) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS PaymentsTotal, ( SELECT SUM(reda.Refunds) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS Refunds, ( SELECT SUM(reda.RefundTotal) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS RefundsTotal, ( SELECT SUM(reda.OffersOptedInto) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS OffersOptedInto, ( SELECT SUM(reda.RedeemedOffers) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS RedeemedOffers, ( SELECT SUM(reda.RedeemedOfferTotal) FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId) AS RedeemedOfferTotal FROM RetailerDaily reda WHERE (reda.RetailerId = @retailer_id OR @retailer_id IS NULL) AND (reda.DateStart &gt;= @date_from OR @date_from IS NULL) AND (reda.DateStart &lt;= @date_to OR @date_to IS NULL) GROUP BY reda.RetailerId </code></pre> <p>However, when I pass in retailer_id as null I receive the following error message</p> <pre><code>Msg 512, Level 16, State 1, Line 9 Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, &lt;, &lt;= , &gt;, &gt;= or when the subquery is used as an expression. </code></pre> <p>Can anybody shed some light onto how to resolve this issue as I can't seem to work it out.</p> <p>Thanks in advance</p> <p>Steven</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.
