    DEPTNO         ID NAME                     SALARY DNAME
        10          1 clark                        10 ACCOUNTING
        20          1 clark                        15 RESEARCH
        10          2 jones                     13 ACCOUNTING
        20          3 king                         25 RESEARCH
        10          3 king                         25 ACCOUNTING
        10          4 ford                         35 ACCOUNTING
        20          4 ford                         35 RESEARCH
        10          5 scott                        50 ACCOUNTING
        20          6 miller                       50 RESEARCH
        10          7 smith                        50 ACCOUNTING
10 rows selected.
[code]
I want o/p should be like:
{code}
      ID NAME                     SALARY
      1 clark Accounting           10
      1 clark                             15
      2 jones Accounting           13
   2 jones      
                     0
      3 king                              25
      3 king Accounting             25
      4 ford Accounting              35
      4 ford                               35
      5 scott  Accounting          50
  5 scott                           
0
      6 miller                             50
      7 smith Accounting           50
  7 smith                            0
{code}
Logic:
It is group by id.
1- When corresponding to a id, we have names with dname as Accounting and research, then we have to print name +accounting and name.
{code}like: name       dname          sal                     o/p should be like:          name                      sal
               clark        accounting      10                                                         clark accounting       10
               clark         research         15                                                         clark                        15
{code}
2- If there is only one name and its associated with accounting department, then we have to print name + accounting and one extra row with same name with sal=0.
{code}like: name       dname           sal                    o/p should be like:          name                       sal
               jones        accounting       13                                                      jones accounting        13
                                                                                                              jones                         0
{code}
3- If there is only one name and its associated with research department, then we have to print name only.
{code}like:  name        dname       sal                     o/p should be like:           name                    sal
                 miller         research    50                                                           miller                     50
{code}

Answer 1

Hi,
my fault as I haven't read well the requirements.
Here is the modified version:
WITH got_cartesian AS
   SELECT DISTINCT t.id, t.name, d.deptno, d.dname
     FROM test t CROSS JOIN dept d
    WHERE d.deptno IN (10, 20)
SELECT c.id, c.name||CASE WHEN c.deptno=10 THEN ' Accounting' END name , NVL (t.salary, 0) sal, c.dname
  FROM got_cartesian c LEFT OUTER JOIN test t
       ON (c.id = t.id AND c.deptno = t.deptno)
WHERE c.deptno!=10 OR t.salary IS NOT NULL
ORDER BY c.id, c.deptno;
Output will be like this:
ID NAME                              
SAL DNAME   
1 clark Accounting                   
10 ACCOUNTING   
1 clark                              
15 RESEARCH
2 jones Accounting                   
13 ACCOUNTING   
2 jones                               
0 RESEARCH
3 king Accounting                    
25 ACCOUNTING   
3 king                               
25 RESEARCH
4 ford Accounting                    
35 ACCOUNTING   
4 ford                               
35 RESEARCH
5 scott Accounting                   
50 ACCOUNTING   
5 scott                               
0 RESEARCH
6 miller                             
50 RESEARCH
7 smith Accounting                   
50 ACCOUNTING   
7 smith                               
0 RESEARCH  
Regards.
