Hi there,
again I'm trying to examine one of our tables with some similar coloumns and their correlations.
After counting with grouping sets in a sub query I try to number the result rows ("lfd_nr") and to cumulate the counted numbers ("anzahl" / "anz_kum") by partitioning the results (one window for each grouping set).
| Code: |
SELECT ROW_NUMBER()
OVER (PARTITION BY b.cols_flag
ORDER BY b.cols_flag ASC
, b.col_alpha
, b.col_bravo
, b.col_charlie )
ldf_nr
, b.cols_flag
, b.col_alpha
, b.col_bravo
, b.col_charlie
, b.anzahl
, SUM(b.anzahl)
OVER (PARTITION BY b.cols_flag
ORDER BY b.cols_flag ASC
, b.col_alpha
, b.col_bravo
, b.col_charlie
ROWS UNBOUNDED PRECEDING )
anz_kum
FROM (SELECT a.col_alpha
, a.col_bravo
, a.col_charlie
, a.anzahl
, DECODE(a.col_alpha , NULLIF('{}', '{}'), 'X', ' ')
||DECODE(a.col_bravo , NULLIF('{}', '{}'), 'X', ' ')
||DECODE(a.col_charlie, NULLIF('{}', '{}'), 'X', ' ')
cols_flag
FROM (SELECT col_alpha
, col_bravo
, col_charlie
, COUNT(*) anzahl
FROM my_table
GROUP BY GROUPING SETS
( ( col_alpha )
, ( col_bravo )
, ( col_charlie))
) a
) b
WITH UR

I did several trys with one and two sub queries but none of them were successfull. Whatever i tried, the windows partition clause did not work.
So, the results I got and what I still desire to get I show you in the following table.
| Code: |
LDF_NR LDF_NR COLS_FLAG COL_ALPHA COL_BRAVO COL_CHARLIE ANZAHL ANZ_KUM ANZ_KUM

Little explanation: {} means NULL.
In the past I was successful with several other ROW_NUMBER and aggregate function usages but this time I don't have any idea why the windows partition clause does not work.
As you can see the auxiliary coloumn COLS_FLAG looks pretty good. But why is it ineffective in the partition clauses?
I guess it's a bungling mistake and a very simple thing. Like it was in my question in thread #66500...
Thank you all for your help |
