David,

I basically agree with your arguments, yet all we've said in this respect is mostly speculation. However, to claim that the OLE-DB provider for Fox renders results that much more different than Fox itself is a far stretch, to say the least. A demonstration to the contrary would be most interesting nonetheless.
Actually, if that were true then perhaps we should access the data through the Fox OLE-DB from VFP itself :)

Remember that the OLE-DB driver is a stripped-down VFP engine that is quite different in many ways, including the removal of many, many commands and functions.
