You can do something like
select to_char(date_column,'YYWW'), count(*), sum(other_column)
from table
where date_column between date1 and date 2
group by to_char(date_column,'YYWW')
where WW returns the week of the year ( 1 to 53)
keeping in mind, of course, that you must include in the group by any
column in the select which does not have a group function on it (sum, max,
min, avg, etc).
