Need help in GROUPING of COLUMN Based Query

Question

Hi,
I am facing problem in generating a scenario:
I have built a Query like this:
SELECT
a.sal,
a.country
FROM
employee a,
department d
WHERE
a.dept_code=b.dept_code
I want the query where the Query will produce a result set based on SALARY based on COUNTRY.
For example if the COUNTRY is US then it will show the breaking of SALARIES.If the COUNTRY is NON US it will club the SALRIES
Any help will be needful for me

Hi,
Here's one way:
SELECT       deptno
,       SUM (sal)     AS sal
FROM       scott.emp
GROUP BY  deptno
,            CASE
           WHEN  deptno = 30
           THEN  empno
       END
ORDER BY  deptno
;Output:
`   DEPTNO        SAL
        10       8750
        20      10875
        30       1600
        30       1250
        30       1250
        30       2850
        30       1500
        30        950In the table, there are 3 rows with deptno=10, and 5 rows with deptno=20, but the CASE expression returns NULL for all of them, so there is only 1 sub-group for each of those deptnos.

This is essentially the same solution that Jeneesh already posted. (Sorry, I didn't see that before.)
