RE: Help with Group by rollup

Hi all
I have i file with this columns and data

CLSTS CLMST CLCTO CLART CLUB1 CLUB2 CLUB3 CLLSI
A 40 34815 0080502 A01 002 1955
A 40 34815 0080501 A01 003 1955
A 40 34815 0080505 A01 003 1955
A 40 34815 0080501 A01 003 1956




If I run this Sql statement

SELECT CLMST, CLCTO, CLUB1, CLUB2, CLUB3, CLART, cllsi , sum(ClQis)
as Tot,
Grouping(CLMST) As mst,
Grouping(CLCTO) As Cto ,
Grouping(CLart) As Art,
Grouping(CLUB1) As Ub1,
Grouping(CLUB2) As Ub2,
Grouping(CLub3) As Ub3,
GROUPING(cllsi) as lsi
FROM OCLLw00F WHERE CLSTS <>
'C' GROUP BY ROLLUP

( CLMST, CLCTO, CLUB1, CLUB2, CLUB3, CLART, cllsi
)
ORDER BY CLMST, CLCTO, CLUB1, CLUB2, CLUB3, CLART, cllsi

I receive this result

CLMST CLCTO CLUB1 CLUB2 CLUB3 CLART CLLSI TOT MST
