SQL in XML file

Question

hallo all.
i want to give value of groups.id instead of id from groups table. pls, could anybody help me with it.
SELECT * FROM MEMBERS WHERE ID = (SELECT MEMBER_ID FROM MID WHERE GROUP_ID = (SELECT ID FROM GROUPS));
the group.id comes from here, from java file:
if(VIEW_GROUP_MEMBERS_LIST_ACTION.equals(actionName))
{request.setAttribute("groups", inventory.findGroups(id));}
and java takes it from jsp file:
<td><a href="${pageContext.request.contextPath/controller/viewGroupMembersList?id=${groups.id">Members</a></td>
thanks in advance, lema

hi,
<sqlStatement name="Q2"> 
<![CDATA[
SELECT Name
,Age
,Phone
FROM my_table
]]> 
</sqlStatement> 
and
<sqlStatement name="Q2"> 
<![CDATA[
SELECT Name
,Age
,Phone
,Address
,Salary
FROM my_table
]]> 
</sqlStatement> 
can be union as
<sqlStatement name="Q2"> 
<![CDATA[
SELECT &column_list
FROM my_table
]]> 
</sqlStatement>
and so
if you use one SqlStatement section then you don't need to use DataStructure section
all columns from selection will be in output
so you need only dynamic part for columns list
the question is how template will accept dynamic number columns
if number and names of columns only defined set then you can rely on names and template
if number and names of columns then you can't
you must create dynamic template also (may be xslt template)
so your approach is
I created a procedure which would create & update the XML (attached to Data Definition) dynamically for every run. This dynamic XML contains SQL statement for data query which is built dynamically. I am then updating this XML using XDOLoader utility to the Data Definition. Then I am running my custom program to generate the excel output.
so in one concurrent you use shell for updating xml data template by xdoloader
and in second one to run report
but what about template? is it dynamic or contain all max set of columns ?
