have a following query where i'm using a sub select and then summing a column but its not letting me do that becuase sum cannot be applied on a sub select. But when i try to put sum insdide such as sum(cost_ps) then it asks me to put transaction_type_cd in the group by. Is there a way to sum the column while using the sub select and i dont have to put the transaction code in the group by because i dont need to group by the code it gives me wrong results. any kind of suggestion would be appreciated. thanks

select vt.account_sub
,vt.cusip_id
,sum(case
when vt.transaction_type_cd in
(select transaction_type_cd
from tbl_maint_transactions_trans_trans_type_cd
where test='unrealized_gain1_sch3a')
then vt.cost_ps
when vt.transaction_type_cd in
(select transaction_type_cd
from tbl_maint_transactions_trans_trans_type_cd
where test='unrealized_gain1_sch3a') and vt.cost_ps > 0
then vt.cost_ps end) as unrealized_gain

from vw_perac_transaction as vt

group by
,vt.account_sub
,vt.cusip_id

try this:

select vt.account_sub
,vt.cusip_id
,sum(case
      when tt.test='unrealized_gain1_sch3a' and vt.cost_ps > 0)
      then vt.cost_ps
      else 0 end) as unrealized_gain

from vw_perac_transaction as vt left join tbl_maint_transactions_trans_trans_type_cd as tt
on vt.transaction_type_cd = tt.transaction_type_cd
group by
,vt.account_sub
,vt.cusip_id

I do not understand what are you trying ti get with 2 when clauses in the sum. Maybe the query is not what you want to get.

Let me know if that the case and I can adjust the query for you.
