Thank you, Marty!
I don't know what was the problem, I was doing almost the same. Now it
works.

Subject: RE: Cocoon2: couldn't make nested queries work for ESQL in XSP.
I've done a number of nested queries in C1.8.2 and as far as I know the
approach is the same in C2. Here is an example:
esql:execute-query
!-- for each rid in Collection - get the centity's --
!-- SQL Server query
SELECT DISTINCT Contribute.centity_id, Contribute.role
FROM Contribute INNER JOIN
Collection_resources ON Contribute.rid =
Collection_resources.rid
WHERE (Collection_resources.Collection_id = 18)
--
esql:queryselect Distinct Contribute.Centity_id, Contribute.role
FROM Contribute , Collection_resources where
Collection_resources.Collection_id=xsp:exprcollectionID/xsp:expr and
Collection_resources.rid=Contribute.rid/esql:query
esql:error-results
!-- error-results occur when there is a sql error --
!-- db connection errors are thrown to xsp --
!-- stacktrace is shown for errors in xsp --
errorSQL error - contact the ilumina
administrator/error
/esql:error-results
esql:results

esql:row-results

centityIDesql:get-int column=1//centityID
roleesql:get-string column=2//role
!-- get the count --
esql:execute-query
esql:queryselect count(distinct Contribute.rid) from Contribute,
Collection_resources where centity_id=esql:parameter
type=intesql:get-int ancestor=1 column=1 //esql:parameter and
Contribute.rid=Collection_resources.rid and
Collection_resources.Collection_id=xsp:exprcollectionID/xsp:expr

Subject: Cocoon2: couldn't make nested queries work for ESQL in XSP.
I've to make a report on the table M, then for each row I
need to show corresponding rows from tables F and C.
Something like this:
rowset name=M
row
ID1/ID
rowset name=F
row
f_namef1/f_name
row
...
/rowset
rowset name=C
row
c_namec1/c_name
row
/rowset
/row
...
/rowset
I tried this :
esq
l:parameter type=intesql:get-int ancestor=1
column=id//esql:parameter
It didn't work with an exception:
org.apache.cocoon.ProcessingException: Exception in
ServerPagesGenerator.generate(): java.lang.RuntimeException:
Error executing prepared statement: select ... from f where M_ID = ? :
java.sql.SQLException: ORA-01722: invalid number
Can somebody give me a WORKING and tested example of nested
queries in Cocoon2?
thanks,
Argyn
