John, Yes, it can be done with the SQL user-defined function. Let SQL server do all the work (check for null, filter records between date parameters) before it sends you the records across the wire. The UDF will accomplish this very nicely for you. Let me know if you need help in moving forward with this direction.

I dunno. I have a view in SQL Server returning 8 fields, 6K records (currently), completely unfiltered, all records in the table. I pull that linked table into a query in order to do some preliminary filtering - check date between a pair of dates and check number not null. I want the view in sql server to do the "check number not null" for me, and I know how to do that. I want the SQL Server to take a pair of parameters - "From Date" and "To Date" and return only those records. If I could do this, then I could get rid of my "base query" in access which applies these filters, reduce traffic across the wire etc. However even if I do this, the view is not being requested by a form in XP (for example) where some magical thing happens in Access to pass the parameters off to SQL Server. The linked view will be used immediately in another query which joins this view to other tables (on one field - BEID - in the view) in order to build up a set of data for a report. So the "parent" query that is using the view will have to "feed" the parameters to the linked view. Being a nubee to SQL Server I do not even know if what I am attempting to do is possible. I cannot wrap my mind around how a query that is using a view can know that the view needs parameters, and if it did, what to feed it. If it is possible, I have never done so obviously, so I don't even have the basics of what to set in Access to do the parameter passing. John W.
