dear ali,
something like
select machine,date_part('day' , date) , sum(withdrawals) from
Table where date_part('month' , date)='month in question' group by
machine,date_part('day' , date) ;
will give you agrregated withdrawals by machine and day,
use the frontend language for formatting it.
note that it will not display the days for which there
has been no withdrawls. If u need to report them also 0
then create a table that holds 1 year of dates and
left or right join the output of first query with it.
exact query is not being provided , its just an idea.
regds
mallah.
