## Unanswered: How to retrieve the max sequence number

Hi,
I have the following values in my table

agnum sitenum month year sequence values
100 010 05 2003 1 50
100 020 05 2003 1 50
100 030 05 2003 1 50
100 040 05 2003 1 50
100 050 05 2003 1 50
100 010 05 2003 2 60
100 020 05 2003 2 40
100 030 05 2003 2 40

The out put that i would like is :
agnum month year sum(values)
100 05 2003 240 ( 60+40+40+50+50)

ie: I want the total of all the values for the sites which have the max( sequence) eg: site 010,020,030 have sequence 2 . So i want the total to include only the values of 010,020,030 with sequence 2 and it should include the values of site 040,050 with sequence 1 since site 040,050 donot have a resubmission for the month 05/2003

Any help is much appreciated

## Required Query

Jayanti
Kindly use the following query to get the answers.

select a.agnum, sum(a.values1) from table1 a, (select max(sequnce) maxseq, sitenum from table1 group by sitenum) tmptable where a.sequnce=tmptable.maxseq and a.sitenum=tmptable.sitenum group by a.agnum;

In order to get the max sequence number for all the sitenum, you would use the following query
select max(sequnce) maxseq, sitenum from table1 group by sitenum;

Thanx and Regards
