Hello group, hello Christian Haul, hello Tim Myers, hello Leo Leonid, here is my small summary (I will put it in the wiki ;-)).
problem: I am using a RDBMS. I have two queries where the second query should use the result of the first. example (working one): my.xsp: <xsp:page language="java" xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2" xmlns:xsp-request="http://apache.org/xsp/request/2.0"> <dataset> <esql:connection> <esql:pool>OSTMDB</esql:pool> <!--First query--> <esql:execute-query> <esql:query> select ap_id as id from sales </esql:query> <esql:results> <esql:row-results> <data> <ep1> <esql:get-int column="id"/> </ep1> <!--Second query which should dynamic --> <aps> <esql:execute-query> <esql:query> select * from ap_tab where ap_id =1 </esql:query> <esql:results> <esql:row-results> <ap> <esql:get-columns/> </ap> </esql:row-results> </esql:results> <esql:no-results> <no-results/> </esql:no-results> <esql:error-results/> </esql:execute-query> </aps> </data> </esql:row-results> </esql:results> <esql:no-results/> <esql:error-results/> </esql:execute-query> </esql:connection> </dataset> </xsp:page> Suggestions from the list: a) Christian wrote (Mail: Multiple ancestors): select * from ap_tab where ap_id = <esql:parameter type="int"><esql:get-int column="id" ancestor="1"/></esql:parameter> Status => not working! I don't receive any error messages. It is just working without any result (besides CPU-usage 100%). I tried with 2 different db (big and small) but neither were working :( -> thanks for the support, anyway. :) => modifying the query like: <esql:parameter><esql:get-int column="id" ancestor="1"/></esql:parameter> will not result in an error but neither I receive the data of the contact person! b)Tim wrote (Mail: Re: esql nested queries): "You need a <xsp:logic>int ap_id = <esql:get-int column="id"/> before the inner query begins and then use <xsp:expr>ap_id</xsp:expr> in the inner query to recall it." => That is working fine with the small and big db! So the final my.xsp looks like that: <xsp:page language="java" xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2" xmlns:xsp-request="http://apache.org/xsp/request/2.0"> <dataset> <esql:connection> <esql:pool>INSTA</esql:pool> <!--note--> <esql:execute-query> <esql:query> select ap_id as id from xml_verkauf </esql:query> <esql:results> <esql:row-results><xsp:logic>int xid =<esql:get-int column="id"/>;</xsp:logic> <data> <ep1> <xsp:expr>xid</xsp:expr> </ep1> <!--note--> <aps> <esql:execute-query> <esql:query> select * from ap_tab where ap_id =<xsp:expr>xid</xsp:expr></esql:query> <esql:results> <esql:row-results> <ap> <esql:get-columns/> </ap> </esql:row-results> </esql:results> <esql:no-results> <no-results/> </esql:no-results> <esql:error-results/> </esql:execute-query> </aps> </data> </esql:row-results> </esql:results> <esql:no-results/> <esql:error-results/> </esql:execute-query> </esql:connection> </dataset> </xsp:page> Thank you for the hints you gave me! Tim, thanks for actually SOLVING MY problem.
