Retrieving the last record in each group
I have one table, which has three fields and data.
Name , Top , Total cat , 1 , 10 dog , 2 , 7 cat , 3 , 20 horse , 4 , 4 cat , 5 , 10 dog , 6 , 9
I want to select the record which has highest value of Total
for each Name
, so my result should be like this:
Name , Top , Total cat , 3 , 20 horse , 4 , 4 Dog , 6 , 9
I tried group by name order by total, but it give top most record of group by result. Can anyone guide me, please?
Solution 1:
select
Name, Top, Total
from
sometable
where
Total = (select max(Total) from sometable i where i.Name = sometable.Name)
or
select
Name, Top, Total
from
sometable
inner join (
select max(Total) Total, Name
from sometable
group by Name
) as max on max.Name = sometable.Name and max.Total = sometable.Total
Solution 2:
You can try something like
SELECT s.*
FROM sometable s INNER JOIN
(
SELECT Name,
MAX(Total) MTotal
FROM sometable
GROUP BY Name
) sMax ON s.Name = sMax.Name
AND s.Total = sMax.MTotal
