Add cols to query

Question

I have this query:
select state_name,sum(cnt_active) TotalActiveVouchers, sum(sum_active) TotalActiveValue,
sum(cnt_inactive) TotalOtherVouchers, sum(sum_inactive) TotalOtherValue,
sum(cnt_expired) TotalRedeemedVouchers, sum(sum_expired) TotalRedeemedValue
from(select state_name,decode(mp.status,'12',1,0) cnt_active,
decode( mp.status,'12',mh.chargesheet_name,0) sum_active,decode(mp.status,'18',1,0) cnt_inactive,
decode( mp.status,'18',mh.chargesheet_name,0) sum_inactive,
decode(mp.status,'',1,'5',1,'16',1,'17',1,0) cnt_expired,
decode( mp.status,'',mh.chargesheet_name,'5',mh.chargesheet_name,'16',mh.chargesheet_name,'17',mh.chargesheet_name,0) sum_expired
from mst_pindetails mp, mst_batchno mb,mst_chargesheet_hdr mh,
mst_state ms where mp.swhbatchcode=mb.swhbatchcode and mb.chargesheetno = mh.chargesheet_code and trim(ms.state_id) = mb.statecode)
group by state_name order by state_name
This query displays results of statename,active count, active value,redeem count, redeemvalue, other count, othervalue
I want two more columns to be displayed status and attribute_date which come from mst_pindetails table ... i dont want to use them in groupby
I need these because if i add these two cols also to this query i can use it in an application where i can perform the search criteria based on these two... if they are in the query then only i will be able to use it in application

Answer 1

it gives me 60740 rows .... actually i should get only 6 rows based on statename... only 6 states are there,.... but different status and attribute_date are there thats why iam getting more rows ... can i get only 6 states and can i make status and attribute date as null when results are displayed
how to set a column value to null or zero in the results displayed..just use your original query and add null as status and null as attribute_date
that will give you the columns with no value.
