I am trying to select data from a history file. There may be multiple records on a day, and I only want to select the record with the last time for the each date in the date range.

PREM Batch RDATE RTIME
100 MR07 20181212 100000
100 MR07 20181212 110020
100 MR07 20181213 100000
101 MR08 20181212 100000


The basics are
Select * from hstread00 where rdate between 20181212 and 20190101 and batch <> 'ORTE' and prem = '100'

I've can manage a single max date, or a single max time for the PREM, but I need the max time for each date for each PREM

Any help appreciated.

Mike
