The Virtuoso blogging system allows to insert into a post a result from SQL, XPATH or XQuery expressions. The way this can be done is to have a SQL access enabled for the Web user making the post, so such blogger can insert into a post body (note that this is not available for title) a XMLTemplate. (see "XML Templates" for reference) Then at the render time the template will be executed on behalf of the blogger who is made the post and result will be shown. There is no limitation how many XML Templates can be included in a single post. Please note that bloggers without SQL access cannot do such posts. Also the SQL granting rules will be applied when XML Template is executed.

The following will render a simple table containing list of Demo.demo.Shippers table from Demo database.

            <table border="1">
                <sql:query xmlns:sql="urn:schemas-openlink-com:xml-sql" >
                    select 1 as tag , null as parent, CompanyName as [tr!1!td!element]
                    from Demo.demo.Shippers
                    for xml explicit

The following post will render a table containing a names of people which is organized in simple OPML file (located in the tutorial system) using XQuery.

                <sql:xquery  xmlns:sql="urn:schemas-openlink-com:xml-sql"
                    <table border="1">
                        { for $o in document ("opml.xml")//outline
                           return <tr><td>{ string ($o/@text) }</td></tr>
