Hi,

have you tried to use a CTE for your SQL-Statement and specify RANK in the
final select?

With x as (YourSelect-Statement)
Select "Customer Name", "Rank 1", Rank() Over(Order By "Rank1) ....

From x

Mit freundlichen Grüßen / Best regards

Betreff: Ranking results

I am trying to figure out how to rank sales figures.  The report would
return Q4 sales for 2009, 2009, 2007 with rankings varying for each year
depending on sales.  I was trying to use Rank() but " An OLAP function
is not supported for this query.".

SELECT
       AMFLIB . CUSMAS . CUSNO AS "Customer Number" , AMFLIB . CUSMAS .
CUSNM AS "Customer Name" ,
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1091001 AND
1091231 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 12/31/09" ,
       0 AS "RANK 1",
       --RANK() OVER (ORDER BY SUM ( CASE WHEN AMFLIB . MBF9REP .
FEGHNB BETWEEN 1091001 AND 1091231 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0
END ) ) AS "RANK 1",
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1081001 AND
1081231 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 12/31/08" ,
       0 AS "RANK 2",
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1071001 AND
1071231 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 12/31/07" ,
       0 AS "RANK 3",
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1100101 AND
1100331 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 03/31/10" ,
       0 AS "RANK 4",
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1090101 AND
1090331 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 03/31/09" ,
       0 AS "RANK 5",
       SUM ( CASE WHEN AMFLIB . MBF9REP . FEGHNB BETWEEN 1080101 AND
1080331 THEN AMFLIB . MBDDREP . DDDUVA ELSE 0 END ) AS "QE 03/31/08",
       0 AS "RANK 6"
