Adding hard coded column values to a result set.

Question

DB version:10gR2
Example from sample schema SCOTT
select e.ename, e.empno, d.loc
from
emp e inner join dept d on (e.deptno=d.deptno)
and e.ename like 'M%';
ENAME           EMPNO LOC
MARTIN           7654 CHICAGO
MILLER           7934 DALLAS
For every ename like 'MARTIN' the following two rows (hardcoded column values 001-985 and 003-745 ) should get created.
PAY_TYPES   PAY_CODES               
   001           985               
   003           745    
   Everything else must remain same.
The result set should look like the following. Here two rows got created for MARTIN and MILLER.Everything else remains the same
  ENAME           EMPNO  PAY_TYPES   PAY_CODES               LOC
  MARTIN           7654  001           985               CHICAGO
  MARTIN        7654  003           745                       CHICAGO
  MILLER           7934  001           985                  DALLAS
  MILLER           7934  003           745                  DALLAS
  How is this possible?

Hello Scott,
Try this,
SELECT ENAME, EMPNO, PAY_TYPES, PAY_CODES, LOC
  FROM (SELECT K.*, ROW_NUMBER() OVER(PARTITION BY ENAME ORDER BY ENAME) ID
          FROM (SELECT *
                  FROM (SELECT ENAME, EMPNO, LOC
                          FROM EMP E, DEPT D
                         WHERE E.DEPTNO = D.DEPTNO
                           AND ENAME LIKE 'M%')
                 WHERE CONNECT_BY_ISLEAF = 1
                CONNECT BY LEVEL <= 2) K)
MODEL
   DIMENSION BY (ENAME, ID)
   MEASURES ( EMPNO, LOC, '000' AS PAY_TYPES, '000' AS PAY_CODES )
   RULES    ( PAY_TYPES[FOR (ENAME) IN (SELECT ENAME FROM EMP WHERE ENAME LIKE 'M%' ),1] = '001' ,
              PAY_CODES[FOR (ENAME) IN (SELECT ENAME FROM EMP WHERE ENAME LIKE 'M%' ),1] = '985' ,
              PAY_TYPES[FOR (ENAME) IN (SELECT ENAME FROM EMP WHERE ENAME LIKE 'M%' ),2] = '003' ,
              PAY_CODES[FOR (ENAME) IN (SELECT ENAME FROM EMP WHERE ENAME LIKE 'M%' ),2] = '745' )   Regards,
