>The tables were upsized into Sql Server from VFP DBC using the ltest Sedna Upsizing Wizard. VFP Date fields were converted to DateTime, but I assume you can still use Max() and Min() on DateTime fields, so let's hope that will work fine.

FYI: Sql Server 2008 has a date field type. I would use that instead of DateTime fields for your VFP date fields.
