Hallo,

I am using the following select statement;

select entity,((sum(bytes)/1024)/1024) as MB from summary where entity
in (select node_name from nodes where domain_name like 'DM%') and
start_time>timestamp(current_date - 1   days) and activity='BACKUP'
group by entity


I would like to be able to specify a period of hours preceding the
current date/time, rather than a whole number of days [
timestamp(current_date - 1   days)  ]. My SQL's not so hot, if anyone
could show me how to do it I would be very grateful.

Thanks,

Matt.
