[SQL] FW: Help- post gress sql error

Hi!

I am receiving the following error when trying to execute sql

--------------------
Error: ERROR: ExecSubPlan: failed to find placeholder for subplan
result (State:HY000, Native Code: 2C)
---------------------

My query works fine in Oracle database without any issues.

I have sub queries with in the sql. If I replace sub queries with hard
coded values query works fine.
---------------------
select ft.a_id
,sum(nvl(ft.t_amt,0)) fee
from a_tran ft
,c_sum c1
,( select c.a_id,max(c.c_end_date)as end_date
from c_sum c
where c.d_status_id not in (7,10)
and c.c_end_date between '01-jun-2008' and '31-jul-2008'
group by c.a_id) prev
where ft.a_id=prev.a_id
and c1.a_id=prev.a_id
and c1.c_end_date=prev.end_date
and ft.p_date between '01-jul-2008' and '31-jul-2008'
and (( ft.t_code in ( select fld1_source_value from tran_code)
)
OR ( ft.t_code in ( select fld1_source_value from tran_code_2)
and ft.t_description not in (
select tran_dscr from tran_code_dscr)
)
)
and ft.p_date between c1.c_start_date and c1.c_end_date group by
ft.a_id;
----------

Please advice if there is any setting that can be made to avoid this
problem.

Thanks,
Prasoona
