title: How can I make MS Access Query Parameters Optional?
body: <p>I have a query that I would like to filter in different ways at different times.  The way I have done this right now by placing parameters in the criteria field of the relevant query fields, however there are many cases in which I do not want to filter on a given field but only on the other fields.  Is there any way in which a wildcard of some sort can be passed to the criteria parameter so that I can bypass the filtering for that particular call of the query?</p>
