Using Access 2002, I have a table with a date field.  I want to setup a paramter query that will either pull data as of a certain date entered or pull all data if no date is entered.  I can get the first part, but when no value is keyed I get no results.  How can I do this?

Change YourDateFieldName to the Name of your actual date field.

SELECT Table1.*
FROM Table1
WHERE (((Table1.YourDateFieldName)=IIf(IsNull([Enter Date]),[YourDateFieldName],[Enter Date])));
