Parameter Fields - Date/Time to Date

I need to filter my report by some date fields.  I created a parameter field for the database field and tried to select "Date" type.  However, when I fill in the rest of the info and click "Ok", then open it again, none of the info is retained.  Only if I set the type to "Date Time" will the parameter field work.

The problem is that, when the report gets diplayed and the prompt opens to enter or select the date(s), a time (0:00:00) is required to be typed in (or automatically added if the calendar is used).

How do I set it up so only a date is required?

TIA

You can use a date parameter.

WHat field are you comparing to?  What data type is it?

You can filter with a formulalike

Date({YourDateTimeField}) = {?Date1}

That's what I thought.  However, it doesn't appear to work.

The field is a SQL Server Datetime data type.

I create a new Parameter Field, type in it's name, select "Date" for the Type, select the proper field in the Value Field listbox, then I select "Allow range values" in the Options and click "Ok".

Reopening the Parameter Field with "Edit", the Value Field is set to "(None)"

There is a problem with handling DateTime and Date types in Crystal Reports.

I would recommend creating a DATE parameter for nice entry. Use this parameter field in a formula field which converts the value to a DateTime field and use this formula as parameter for your query.

Since the field type is really DATETIME I suspect Crystal doesn't maintain it.  That value in the parameter screen is only used to be able to load the values.

Are you using a dynamin or static parameter?

You can use parameters in the SELECT EXPERT to filter the data for the report.
