dynamic query with esql

[Franco Andrao]

Hi, I'm trying to pass variables from the results of a query to another query in the same xsp page: this is the code <?xml version="1.0"?> <xsp:page language="java"           xmlns:xsl="http://www.w3.org/1999/XSL/Transform"           xmlns:xsp="http://apache.org/xsp"           xmlns:esql="http://apache.org/cocoon/SQL/v2"           xmlns:xsp-request="http://apache.org/xsp/request/2.0"> <text>     <xsl:param name="id_rst"/>     <esql:connection>         <esql:pool>teosoficaDB</esql:pool>         <xsl:if test="$id_rst">                <esql:execute-query>             <esql:query>SELECT rst_child FROM relstruttura                         WHERE id_rst=<esql:parameter><xsp-request:get-parameter name="id_rst"/></esql:parameter>             </esql:query>             <esql:results>                    <esql:row-results>                     <esql:get-string column="rst_child"/>  <!-- this is the value I want to use below in the page -->                 </esql:row-results>             </esql:results>             </esql:execute-query>             <esql:execute-query>                 <esql:query>SELECT st_tit,id_rst FROM dbstruttura,relstruttura                         WHERE dbstruttura.id_sez=relstruttura.rst_child AND                         rst_parent=<esql:parameter><xsp-request:get-parameter name="id_rst"/></esql:parameter>                 </esql:query>             <esql:results>                     <esql:row-results>                         <esql:get-string column="st_tit"/>                     </esql:row-results>             </esql:results>             <esql:no-results>                 <esql:execute-query>                 <esql:query>SELECT ar_tit,id_art FROM dbarticoli                             WHERE ar_sez=  <!-- PARAM!! here the value of column rst_child of the first query -->                 </esql:query>                 <esql:results>                        <esql:row-results>                         <esql:get-string column="ar_tit"/>                     </esql:row-results>                 </esql:results>                         </esql:execute-query>             </esql:no-results>             </esql:execute-query>         </xsl:if>     </esql:connection> </text> </xsp:page> The code is working if I use test values for the last query but I don't know how to set a local variable with the value of the esql:get-string ....
