I have a table that handles a competition where I want to pick one winner every day (make it as a daily job running on the SQL-server)

How can I make a query that solves this: If I have a table witt all the answers and one column named dailywinner (If 1 = winner)

I tried this but it updates all the records..

Update dbo.Kalender_svar
Set dailywinner = 1  
where  exists (
Select Top 1 dailywinner
FROM         dbo.Kalender_svar
WHERE     (Dag + 1 = DATEPART(d, GETDATE()))
ORDER BY NEWID())
