query on CSUM - response (5) by vuyyuru

Hi Dieter,
 
We are trying to find the missing dates from the source table with the sys calendar date.
the query is like below.
 

SEL NAME, MEASURE, DATE,

SUM(MEASURE) OVER(PARTITION BYNAMEORDERBYDATEASCROWSUNBOUNDED PRECEDING) ASCUM_AMT

FROM<<TABLE_NAME>>

ORDERBYNAME, DATEASC;

but this is going to product join....  is there any alternate is there for this quwery design..
because my actual source table is having 139 M records... so it will take longer time ( 5 hrs)..
Regards,
Ramaiah
