I can increase the OPEN_CURSOR parameter to 800 or 1000 but sometime
this query can return more than 2000-3000 rows.

I can return the result as an array but its going to be slower than
returning it as a cursor.

SELECT po.prod_offer_id, pot.dscr, po.qual_req, po.prod_id, pt.dscr
,
       CURSOR (SELECT pi.prod_iden_id, pi.parent_id, pit.dscr, pi.VALUE
                 FROM PROD_IDEN pi, PROD_OFFER_IDEN poi, PROD_IDEN_TYPE
pit
                WHERE pit.prod_iden_type_id =3D pi.prod_iden_type_id
                  AND pi.prod_iden_id =3D poi.prod_iden_id
                  AND poi.prod_offer_id =3D po.prod_offer_id
              )
                          ,
       CURSOR (SELECT bt.dscr
                 FROM BILLING_TYPE bt, PROD_BILLING_TYPE pbt
                WHERE bt.billing_type_id =3D pbt.billing_type_id
                  AND pbt.prod_offer_id =3D po.prod_offer_id
              )
  FROM PROD_OFFER po,
       PROD_OFFER_TYPE pot,
       PROD p,
       PROD_TYPE pt,
       PROD_OFFER_AUDNC_PRFLE poap
 WHERE po.prod_offer_type_id =3D pot.prod_offer_type_id
   AND po.prod_id =3D p.prod_id
   AND pt.prod_type_id =3D p.prod_type_id
   AND po.prod_offer_id =3D poap.prod_offer_id
   AND poap.audnc_prfl_id =3D 16
   AND pt.dscr IN ('LD')

There is no way, you have  increase the open_cursor parameter, I have
set to
800.=20

Why do you want to use word CURSOR here? Get rid off it and it should be
fine.

When I execute the following query, the number cursors opened increase
with the number of rows returned by the query and I get the oracle error
"maximum cursor opened".=3D20
=20
Is there a way I can reuse the already opened cursor and not hit the
maximum OPEN_CURSOR value?
