Question

As a beginner in Sql Server 2005, i should get some help in getting top 10 from a table.

The scenario is like, a table Invitecount has multiple records for each userid. i have distinct userid’s with the following sql query

Select distinct(userid) from inviteCount 

For each userid, i get the number of points using the following query

Select sum(points) from invitecount 
where UserID = 126429

And after i get the sum, i should have top 10 users with max points. My problem here is with writing all these statements together using arrays, etc.

IF someone could help me, i really appreciate it. Thanks in advance!

Answer 1

You want something like:

select top 10
    userid,
    pointstotal = sum(points)
from
    invitecount
group by userid
order by sum(points) desc

Note the order by.

A fancier version would be

select 
    userid
    pointstotal = sum(points) over (partition by userid),
    row_number = row_number() over (partition by userid order by sum(points) desc)
from 
    invitecount i
where 
    row_number <= 10

(untested – so probably needs a tweak)
