    <p>Assume you have a highly synthetic task to print numbers from 1 to 1.000.000 without appropriate input XML. Of course, straight-forward recursion will fail due to, ironic enough, stack overflow.</p> <p>I came up with the solution listed below:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt; &lt;xsl:output method="text"/&gt; &lt;xsl:variable name="end" select="number(1000000)"/&gt; &lt;xsl:template match="/"&gt; &lt;xsl:call-template name="batches"/&gt; &lt;/xsl:template&gt; &lt;xsl:template name="batches"&gt; &lt;xsl:param name="start" select="number(1)"/&gt; &lt;xsl:param name="stop" select="$end"/&gt; &lt;xsl:param name="ololo"/&gt; &lt;xsl:if test="$start &amp;lt;= ($end)"&gt; &lt;xsl:choose&gt; &lt;xsl:when test="$stop = 0"&gt; &lt;xsl:value-of select="$start"/&gt;:&lt;xsl:value-of select="$ololo"/&gt; &lt;xsl:text&gt;&amp;#xa;&lt;/xsl:text&gt; &lt;/xsl:when&gt; &lt;xsl:otherwise&gt; &lt;xsl:call-template name="batches"&gt; &lt;xsl:with-param name="start" select="$start"/&gt; &lt;xsl:with-param name="stop" select="floor($stop div 2)"/&gt; &lt;xsl:with-param name="ololo" select=" 'A' "/&gt; &lt;/xsl:call-template&gt; &lt;xsl:call-template name="batches"&gt; &lt;xsl:with-param name="start" select="floor($stop div 2) + $start + 1"/&gt; &lt;xsl:with-param name="stop" select="floor($stop div 2)"/&gt; &lt;xsl:with-param name="ololo" select=" 'B' "/&gt; &lt;/xsl:call-template&gt; &lt;/xsl:otherwise&gt; &lt;/xsl:choose&gt; &lt;/xsl:if&gt; &lt;/xsl:template&gt; &lt;/xsl:stylesheet&gt; </code></pre> <p>It works both in libxslt and MSXML. But it prints some duplicate numbers and looks quite awkward in terms of efficiency. Can this be improved somehow?</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).
