Hi,

I have a following  table

consumerno                   billdate                   billamount
54321                              01/01/2011          100
54322                               15/01/2011            50
54321                               02/02/2011              175
54322                               03/02/2011             100


i want a query that will give me bill amount for a consumerno with latest bill date.

i,.e.
consumerno                billdate                           billamount
54321                             02/02/2011                   175
54322                              03/02/2011                  100

If this is SQL Server 2005+ then you can use row_number()

select consumerno, billdate, billamount
from
(
select *, row_number() over (partition by consumerno order by billdate desc) as rownum
from tbl
) SQ
where rownum=1

>what if i want total billamount ?

In that case, for the exact 3 columns required, a simply group by would suffice.

select consumerno, max(billdate) billdate, sum(billamount) totalamount
from tbl
group by consumerno
