    <p>I am looking for a way that I can query a database with multiple SQL Queries and then, once I have the results of the queries (in XML), merge the separate XML together into one XML document, using reverse paths. My reason for doing this is related to the concept of Parallel Details (same data, with different manipulations applied).</p> <p>For example, 3 Queries:</p> <pre><code> SELECT * FROM Customer; SELECT * FROM Purchase_order; SELECT * FROM Line_Item; </code></pre> <p>Query 1 Results:</p> <pre><code> &lt;customer&gt; &lt;cust_id&gt;2&lt;/cust_id&gt; &lt;fname&gt;John&lt;/fname&gt; &lt;lname&gt;Doe&lt;/lname&gt; &lt;/customer&gt; </code></pre> <p>Query 2 Results:</p> <pre><code> &lt;purchase_order&gt; &lt;order_id&gt;2&lt;/order_id&gt; &lt;cust_id&gt;2&lt;/cust_id&gt; &lt;shipped&gt;7/7/2009&lt;/shipped&gt; &lt;/purchase_order&gt; </code></pre> <p>Query 3 Results:</p> <pre><code> &lt;line_item&gt; &lt;line_id&gt;2&lt;/line_id&gt; &lt;order_id&gt;2&lt;/order_id&gt; &lt;quantity&gt;7&lt;/quantity&gt; &lt;/line_item&gt; </code></pre> <p>Desired Output:</p> <pre><code> &lt;collection&gt; &lt;customer&gt; &lt;cust_id&gt;2&lt;/cust_id&gt; &lt;fname&gt;John&lt;/fname&gt; &lt;lname&gt;Doe&lt;/lname&gt; &lt;/customer&gt; &lt;purchase_order&gt; &lt;order_id&gt;2&lt;/order_id&gt; &lt;cust_id&gt;2&lt;/cust_id&gt; &lt;shipped&gt;7/7/2009&lt;/shipped&gt; &lt;/purchase_order&gt; &lt;line_item&gt; &lt;line_id&gt;2&lt;/line_id&gt; &lt;order_id&gt;2&lt;/order_id&gt; &lt;quantity&gt;7&lt;/quantity&gt; &lt;/line_item&gt; &lt;/collection&gt; </code></pre> <p>This looks like it would be easy, but my SQL queries can return a lot of customers, and a lot of purchase orders and line items, and I need to be able to match them all up.</p> <p>I cannot use one SQL Query with Joins that will collect all of this information at once.</p> <p>Has anyone ever seen anything like this done? Any ideas?</p> <p>Thanks.</p>

    1. COYou're suggesting that the SQL query results are in XML? This isn't standard SQL to my knowledge. What server is this?

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.
