Select Query (Grouping) - Help

Question

Hi,
Here is the table (sample)
Table: AmountCode
Code Amount1 Amount2 Amount3 Amount4
ABC 11 23 234 124
ABC      23      567      567      556
XYZ      56      234      235      344
XYZ      55      56      789      7855
AAA      567      12      234      4367
AAA      789      98      6577      4368
BBB                     
I want to sum different Columns in the above table based on the Code Field (grouping). How to write this query?
If Code = ABC
Sum(Amount1) as OutAmount
Sum(Amount2) as InAmount
If Code = XYZ
Sum(Amount3) as OutAmount
Sum(Amount4) as InAmount
If Code = AAA
Sum(Amount1) as OutAmount
Sum(Amount3) as InAmount
If Code = BBB
I want to get OutAmount & InAmount from different Table.
Thanks in advance

Answer 1

try like this..
for Code = BBB, i wrote general summation...
accordingly you can modify this query...
with rt as
(select 'ABC' Code, 11 Amount1, 23 Amount2, 234 Amount3, 124 Amount4 from dual union all
select 'ABC', 23, 567, 567, 556  from dual union all
select 'XYZ', 56, 234, 235, 344  from dual union all
select 'XYZ', 55, 56, 789,7855 from dual union all
select 'AAA', 567, 12, 234, 4367 from dual union all
select 'AAA', 789, 98, 6577, 4368 from dual union all
select 'BBB', null,null,null,null from dual)
select code,
        decode(code,'ABC',Sum(Amount1),'XYZ',Sum(Amount3),'AAA',Sum(Amount1),'BBB',(select sum(sal) from test_emp where deptno = 10),0) OutAmount,
        decode(code,'ABC',Sum(Amount2),'XYZ',Sum(Amount4),'AAA',Sum(Amount3),'BBB',(select sum(sal) from test_emp where deptno = 20),0) InAmount
from rt group by code order by code;
COD  OUTAMOUNT   INAMOUNT
AAA       1356       6811
ABC         34        590
BBB      12786      13237
XYZ       1024       8199 [pre]
