I my have miss lead my question by using the word pivot. I'm not aggragating values but listing the newest 6 jobsTaking data from 6 different rows and displaying it on one row is aggregating.
fyi, this is my first Thread, sorry if I did not provide enough info.Whenever you have a problem, you should post a little sample data (CREATE TABLE and INSERT statements), and the results you want from that data. Explain how you get those results from that data.
Simplify the problem if you can. For example, instead of posting enough data to get the last 6 jobs, how about just the last 3? You can explain that you really need 6, if you think it will matter.
If you can pose a question using commonly available tables, such as those in the scott schema, then you don't have to post any sample data, just the results and the explanation.
For example, say you're using the scott.emp table, which contains this data:
SELECT       deptno
,       hiredate
,       ename
FROM       scott.emp
ORDER BY  deptno
,            hiredate
    DEPTNO HIREDATE  ENAME
        10 09-JUN-81 CLARK
        10 17-NOV-81 KING
        10 23-JAN-82 MILLER
        20 17-DEC-80 SMITH
        20 02-APR-81 JONES
        20 03-DEC-81 FORD
        20 19-APR-87 SCOTT
        20 23-MAY-87 ADAMS
        30 20-FEB-81 ALLEN
        30 22-FEB-81 WARD
        30 01-MAY-81 BLAKE
        30 08-SEP-81 TURNER
        30 28-SEP-81 MARTIN
        30 03-DEC-81 JAMESand you want to pivot this data so that it shows the names of the 3 most recentently hired employees in each department, like this:
`   DEPTNO MOST_RECEN SECOND     THIRD
        10 MILLER     KING       CLARK
        20 ADAMS      SCOTT      FORD
        30 JAMES      MARTIN     TURNER'JAMES' was the last person hired in department 30, 'MARTIN' was the last person hired in deptno=30 before that, and 'TURNER' was the last before that, so on the row for deptno=30 we want 'JAMES', 'MARTIN' and 'TURNER', in that order, and all the others in deptno=30 can be ignored.
Here's one way to get those resuilts:
WITH         got_r_num     AS
     SELECT       deptno
     ,       ename
     ,       ROW_NUMBER () OVER ( PARTITION BY  deptno
                                  ORDER BY          hiredate     DESC
                         )           AS r_num
     FROM       scott.emp
SELECT       deptno
,       MIN (CASE WHEN r_num = 1 THEN ename END)     AS most_recent
,       MIN (CASE WHEN r_num = 2 THEN ename END)     AS second
,       MIN (CASE WHEN r_num = 3 THEN ename END)     AS third
FROM       got_r_num
GROUP BY  deptno
;Whenever you have a question, say which version of Oracle you're using.
The query above will work in Oracle 9 (and up), but starting in Oracle 11 it's better to use the SELECT ... PIVOT feature.
