Hi All,
There is a table that has data loaded from a flat file and is in the following format
RECTYPE     610     570     620     630     640     650     660     LOC_CODE
x     Crawfordsville     CSC     Fort Wayne     Greenfield     LaPorte     Seymour     Vincennes     
2010 Monthly Average     2.6     1.3     2.3     1.7     1     1     1     
1/31/2011     1     1.4     1     2.5     4.6     1.7     3.3     
2/28/2011     1     1     1     5     4     1     4     
3/31/2011     1     1     2.3     3.3     5.3     3.3     3.1

Hi,
Sorry, I don't think there's any way to get exactly what you requested. The values you give in the PIVOT ... IN clause are exact values, not alternatives.
You could do something like this to map all alternatives to a common value:
WITH     got_dept_grp     AS
     SELECT     country_code, job, sal
     ,     CASE
              WHEN  job IN ('SALESMAN', 'MANAGER') AND dept = 301 THEN 30
              WHEN  job IN ('CLERK')               AND dept = 302 THEN 30
                                                                 ELSE dept
          END     AS dept_grp
     FROM     pivot_data
SELECT     *
FROM     got_dept_grp
PIVOT     (     AVG (sal)
     FOR     (job, dept_grp)
     IN     ( ('SALESMAN', 30)
          , ('MANAGER' , 30)
          , ('CLERK'   , 30)
;In your sample data (and perhaps in your real data), it's about as easy to explicitly define the pivoted groups individually, like this:
WITH     got_pivot_key     AS
     SELECT     country_code, sal
     ,     CASE
              WHEN  job = 'SALESMAN' AND dept IN (30, 301) THEN 'd30_sls'
              WHEN  job = 'MANAGER'  AND dept IN (30, 301) THEN 'd30_mgr'
              WHEN  job = 'CLERK'    AND dept IN (30, 302) THEN 'd30_clrk'
          END     AS pivot_key
     FROM    pivot_data
SELECT     *
FROM     got_pivot_key
PIVOT     (     AVG (sal)
     FOR     pivot_key
     IN     ( 'd30_sls'
          , 'd30_mgr'
          , 'd30_clrk'
;Thanks for posting the CREATE TABLE and INSERT statements; that really helps!
