You are not be any chance talking about nesting another query inside
the first? If so, why don't you just try it ? ;-)
<esql:execute-query>
...
<esql:row-results>
<esql:execute-query>
....
</esql:execute-query>
</esql:row-results>
<esql:execute-query>
Can't remember off hand if you need <esql:connection> for your
subquery.
Access values from outer query by using attribute ancestor="1" or
however deep it's nested (e.g. <esql:get-string column="name" ancestor="1"/>)
Or try the grouping stuff (documented on user guide -> XSP -> ESQL)
