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 ....
Thank for your suggestions
