zero records returned when start and end date are the same

When I enter a date range that uses the same for start and end values I get zero records returned al though if I loo in the db I can find a few records that match that criteria.

When I look at the SQL query in Crystal, I see that the record selection date range changes, and the <= show only as < 

Seems this happens automatically on crystal.

How can I avoid that?

Thanks.

Your records probably have a time associated with the date so you need to compare just the date or use

{DateField} >= {?DateParameter} AND {DateField} <= {?DateParameter} + 1

Use a stored procedure.

Also be aware of the times . . . if you have both start and end date @ 12:00 AM then it will only return anything that is exactly at that time.

Interesting point about the <= being changed to <.  That seems to just be the way that CR handles a <= datetime test.  In the query, it adds 1 second to the time and replaces the <= with <.  I don't know why it does that.  My best guess would be some kind of question/problem with precision, or something like that.  So it adds a second and uses < instead.  I don't know if it always does that.  It may depend on your datasource.  In my case I was using a test report that reads an Excel file.

 So
 1) I don't think there's anything you can do to avoid it.  _Maybe_ if you use a different datasource.  I kind of doubt that it would make any difference, but I can't rule it out.
 2) It shouldn't be a problem.  CR is adding 1 second, so the results should be the same.


 The most likely explanation for not finding the records would seem to be what the others suggested, that the times are not within your range.
