I would expect this query to work if the orderdate column is a datetime data
type (although format 'yyyymmdd' is preferred since it is unambiguous). In
the case of char or varchar, string comparison rules are used instead so you
might not get the results you expect.

OK, I guess you noticed that you used the same date for both.

What is the datatype of orderdate?

Looking at ur dates the 2nd part of the and >= should and will only have
items
before 06/21 because time is involved so 06/21/2007 is as of midnite on the
20th
you mite wanna make 06/21/2007 to 06/22/2007 and you should get everything
upto midnite
on the 21st

1. Make sure that the data is set to datetime or smalldatetime
2. Select order from ordertable
where orderdate >= '2007-06-20' and orderdate < '2007-06-21'

or to change the date format with:
SET DATEFORMAT mdy;
then do the query.
