I am very new to MySQL (I tried groupby, but didnt get the result) This my sample data
ticket year status data
111 2007 1 32
111 2007 2 46
111 2007 3 40
111 2007 4 38
111 2009 1 15
111 2009 2 12
115 2009 1 2
115 2009 2 5
I want to select the last entry for each company, for each year. Output should be:
ticket year status data
111 2007 4 38
111 2009 2 12
115 2009 2 5
as status field values looks incremental order. we can simply apply max after groupby.
select a.* from a
inner join (select ticket,year,max(status) as sta from a group by ticket,year) as b
on a.status=b.sta
and a.ticket=b.ticket and a.year=b.year;
