    <p>If possible, insert the document into the database, and in a separate transaction update the nodes using <code>xdmp:node-replace</code>.</p> <pre><code>xquery version "1.0-ml"; ... xdmp:document-insert('file.xml', $file) ; xquery version "1.0-ml"; for $currentNode in doc('file.xml')//ID return xdmp:node-replace($currentNode, element ID{ concat($subject, "-", $currentNode) }); </code></pre> <p>Alternatively, if you have to update the document in memory, it is probably more optimal walking the tree only once (making your updates all in that operation), rather than multiple <code>mem:replace</code> operations (which probably each re-walk the tree).</p> <pre><code>declare function local:update-ids( $n as item(), $subject as xs:string ) as item() { typeswitch ($n) case element(ID) return element ID { concat($subject, "-", $n) } case element() return element { node-name($n) } { @*, $n/node()/local:update-ids(., $subject) } default return $n }; let $xml := xdmp:unquote($file) let $xml-with-updated-ids := local:update-ids($xml, $subject) ... </code></pre> <p><strong>Update:</strong></p> <p>As Erik suggests in the comments, you can also write the logic of <code>local:update-ids</code> in XSLT (using <code>xdmp:xslt-eval</code> or <code>xdmp:xslt-invoke</code> to execute), and they should be roughly equivalent in terms of performance. In fact, MarkLogic has a really well written blog entry on the subject: </p> <p><a href="http://developer.marklogic.com/blog/tired-of-typeswitch" rel="nofollow">http://developer.marklogic.com/blog/tired-of-typeswitch</a></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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
