Trying to translate what a prior employee was doing and have the following:

Where DATEADD(dd, 0, DATEDIFF(dd, 0, PRODDATE)) BETWEEN '02/02/2012' AND '03/03/2013' 
AND 
ORDEREDCOPIES > 0


From what I can tell, the dateadd/datediff isn't actually doing anything. Was just hoping to get a sanity check.

it should have been this


Where DATEADD(dd, DATEDIFF(dd, 0, PRODDATE),0) BETWEEN '02/02/2012' AND '03/03/2013' 
AND 
ORDEREDCOPIES > 0


but a much better way is this


Where PRODDATE >= '2012-02-02' AND PRODDATE < '2013-03-04' 
AND 
ORDEREDCOPIES > 0

To be safe, it should actually be this:

Where PRODDATE >= '20120202' AND PRODDATE < '20130304'
AND
ORDEREDCOPIES > 0
