A specimen stylesheet that uses these XSL extension is books-sql.xsl. This loads the contents of the books.xml file into a database table, To use it, you need to create a database database containing a table "Book" with three character columns, "Title", "Author", and "Category"

Here is the stylesheet:

<xsl:stylesheet
	xmlns:sql="java:/net.sf.saxon.sql.SQLElementFactory"
 	xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
	xmlns:saxon="http://saxon.sf.net/"
 	extension-element-prefixes="saxon sql">

<!-- insert your database details here, or supply them in parameters -->
<xsl:param name="driver" select="'sun.jdbc.odbc.JdbcOdbcDriver'"/>
<xsl:param name="database" select="'jdbc:odbc:test'"/>  
<xsl:param name="user"/>
<xsl:param name="password"/>

<!-- This stylesheet writes the book list to a SQL database -->

<xsl:variable name="count" select="0" saxon:assignable="yes"/>

<xsl:output method="xml" indent="yes"/>

<xsl:template match="BOOKLIST">
    <xsl:if test="not(element-available('sql:connect'))">
        <xsl:message>sql:connect is not available</xsl:message>
    </xsl:if>
    
    <xsl:message>Connecting to <xsl:value-of select="$database"/>...</xsl:message>

    <xsl:variable name="connection" 
         as="java:java.sql.Connection" xmlns:java="http://saxon.sf.net/java-type">   
      <sql:connect driver="{$driver}" database="{$database}" 
                 user="{$user}" password="{$password}">
        <xsl:fallback>
          <xsl:message terminate="yes">SQL extensions are not installed</xsl:message>
        </xsl:fallback>
      </sql:connect>
    </xsl:variable>
    
    <xsl:message>Connected...</xsl:message>
    
    <xsl:apply-templates select="BOOKS">
      <xsl:with-param name="connection" select="$connection"/>
    </xsl:apply-templates>
    
    <xsl:message>Inserted <xsl:value-of select="$count"/> records.</xsl:message>

    <xsl:variable name="book-table">
      <sql:query connection="$connection" table="book" column="*" row-tag="book" column-tag="col"/> 
    </xsl:variable>
    
    <xsl:message>There are now <xsl:value-of select="count($book-table//book)"/> books.</xsl:message>
    <new-book-table>
        <xsl:copy-of select="$book-table"/>
    </new-book-table>
    
    <sql:close connection="$connection"/>
    
</xsl:template>

<xsl:template match="BOOKS">
    <xsl:param name="connection"/>
    <xsl:for-each select="ITEM">
    	<sql:insert connection="$connection" table="book">
    	    <sql:column name="title" select="TITLE"/>
            <sql:column name="author" select="AUTHOR"/>
            <sql:column name="category" select="@CAT"/>
    	</sql:insert>
    	<saxon:assign name="count" select="$count+1"/>
    </xsl:for-each>
</xsl:template>

</xsl:stylesheet>	

To run this stylesheet you will need to do the following:

The database will be populated with data from the books.xml document.
