SQL Servers’ GETDATE() function will return the current DateTime.  But what if you just want the current date.

CAST(FLOOR(CAST(GETDATE() AS float)) AS datetime)

or

CAST(CONVERT(VARCHAR(10), GETDATE(), 111) AS DATETIME)

See this page for even more options.

Or, if you want to get just the current time out of GETDATE or any datetime for that matter, check out this page (it is one of the FAQs).
