Do you really need an actual Ranktable table? I would just use CJ_S query in a view...because as a separate table, think of this scenario:
1. Record gets inserted into stat table for uid = 1
2. insert into Ranktable
repeat steps 1 and 2 a few times
Ranktable is now inaccurate for uid = 1 unless you
1. Delete from Ranktable before you do the insert every time...or
2. Have some kind of autonumber field and query Ranktable with a MAX autonumber where uid = 1 or something....why not just use a view?
CREATE VIEW dbo.Ranktable
AS
SELECT Uid, SUM(Votes) AS TotalVotes, SUM(Views) AS TotalViews
FROM dbo.stat
GROUP BY Uid
Then when you do:
SELECT * FROM Ranktable
it would be accurate
