a 10           10          2 India
a 20          12          3 India
b 30          15          1 India
a 35          20          2 US
b 20          10          1 US
b 60          15          1 US
I woulkd like to split the date based on type column.
For each country, for Type "a" get the sum of revenue count quanity ans same for b
and all shuld come in on row for each country.
output should be like
country revenue_mny(For a) quantity(for a) count(For a) revenue_mny(for b) quantity(for b) count(For b)
India 22 30 5 15 30 1
US 20 35 2 25 80 2
I tried the below query . its not splittng the date for each country in one row.
select country,
sum(case when type='a') then revenue_mny else 0 end ) revenue_mny_a,
sum(case when type='b' then revenue_mny else 0 end ) revenue_mny_b
sum(case when type='a' then quantity else 0 end) quantity_a,
sum(case when type='b' then quantity else 0 end) quantity_b from
test
group by country
Please need your helo

Like this?
with t as
select 'a' type, 10 quantity, 10 revenue_mny, 2 cnt, 'India' country from dual union all
select 'a', 20, 12, 3, 'India' from dual union all
select 'b', 30, 15, 1, 'India' from dual union all
select 'a', 35, 20, 2, 'US' from dual union all
select 'b', 20, 10, 1, 'US' from dual union all
select 'b', 60, 15, 1, 'US' from dual
select country,
sum(case when type='a' then revenue_mny else 0 end ) revenue_mny_a,
sum(case when type='a' then quantity else 0 end) quantity_a,
sum(case when type='a' then cnt else 0 end) cnt_a,
sum(case when type='b' then revenue_mny else 0 end ) revenue_mny_b,
sum(case when type='b' then quantity else 0 end) quantity_b ,
sum(case when type='b' then cnt else 0 end) cnt_b
from t
group by country;result:
COUNTRY  REVENUE_MNY_A QUANTITY_A CNT_A REVENUE_MNY_B QUANTITY_B CNT_B
India    22            30         5     15            30         1
US       20            35         2     25            80         2Or you can do it with a decode instead of case. The result will be the same:
with t as
select 'a' type, 10 quantity, 10 revenue_mny, 2 cnt, 'India' country from dual union all
select 'a', 20, 12, 3, 'India' from dual union all
select 'b', 30, 15, 1, 'India' from dual union all
select 'a', 35, 20, 2, 'US' from dual union all
select 'b', 20, 10, 1, 'US' from dual union all
select 'b', 60, 15, 1, 'US' from dual
select country,
sum(decode(type,'a',revenue_mny,0)) revenue_mny_a,
sum(decode(type,'a',quantity,0)) quantity_a,
sum(decode(type,'a',cnt,0)) cnt_a,
sum(decode(type,'b',revenue_mny,0)) revenue_mny_b,
sum(decode(type,'b',quantity,0)) quantity_b,
sum(decode(type,'b',cnt,0)) cnt_b
from t
group by country;(I changed tablename from TEST to T and columnname from COUNT to CNT, because you should not use reserved words as tablename or columnname.)
