Here is how i would just get the date out of a long date.
declare @NewDate varchar(10)
select @NewDate = convert(varchar(10),getdate(),101)

The site below indicates the parameter values used by MS-SQL for determining the convert output function.

How do I change the code below to filter on today's current date...not 2002-02-22

SELECT TOP 100 PERCENT UserID, LogonTime, IP, ContextID, 'LA_LA_' AS ClientID, SessionID
FROM AAA.dbo.OnlineUser
WHERE CAST(FLOOR(CAST(LogonTime AS float)) AS datetime) = '2002-02-22'
