Hi
DB2 v9.5 z/os
Please find the all scenario and guide me to write a Select query to filter the records.
cond:
1. eliminate all records which VOL_COUNT will have ZERO values
2.Dispaly one record if all records having VOL_COUNT as ZERO values
3. by all the times, the record which is having P.LOC as 'XXX' should be elimated if the NUMBER (NO_FIRST,NO_MID,NO_LAST)
having more than one occurence
4.Dispaly if the number(NO_FIRST,NO_MID,NO_LAST) having the only one record like P_LOC as 'XXX'
Thanks
