    copied!<p>I would recommend using <code>FOR XML PATH</code> instead of <code>FOR XML EXPLICIT</code> - it's much easier to use and much more expressive.</p> <p>See this:</p> <pre><code>-- set up test data declare @Accounts table (AccountID INT, AccountName VARCHAR(50)) declare @Campaigns table (CampaignID INT, AccountID INT, CampaignName varchar(50)) insert into @Accounts values(1, 'Account #1'),(2, 'Account #2') insert into @Campaigns values(1, 1, 'Campaign #1-1'), (2, 1, 'Campaign #2-1'), (3, 1, 'Campaign #3-1'), (4, 2, 'Campaign #1-2'), (5, 2, 'Campaign #2-2') -- SELECT with FOR XML PATH and a nested SELECT/FOR XML PATH,TYPE select AccountID, AccountName, (SELECT CampaignID FROM @Campaigns c WHERE c.AccountID = a.AccountID FOR XML PATH(''),TYPE) AS 'CampaignIDs' FROM @Accounts a FOR XML PATH('Account'),ROOT('Accounts') </code></pre> <p>This <code>SELECT</code> statement gives me the following output:</p> <pre><code>&lt;Accounts&gt; &lt;Account&gt; &lt;AccountID&gt;1&lt;/AccountID&gt; &lt;AccountName&gt;Account #1&lt;/AccountName&gt; &lt;CampaignIDs&gt; &lt;CampaignID&gt;1&lt;/CampaignID&gt; &lt;CampaignID&gt;2&lt;/CampaignID&gt; &lt;CampaignID&gt;3&lt;/CampaignID&gt; &lt;/CampaignIDs&gt; &lt;/Account&gt; &lt;Account&gt; &lt;AccountID&gt;2&lt;/AccountID&gt; &lt;AccountName&gt;Account #2&lt;/AccountName&gt; &lt;CampaignIDs&gt; &lt;CampaignID&gt;4&lt;/CampaignID&gt; &lt;CampaignID&gt;5&lt;/CampaignID&gt; &lt;/CampaignIDs&gt; &lt;/Account&gt; &lt;/Accounts&gt; </code></pre>
