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 Jayanthi

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 Aruneesh
