And that's what I am doing now. So I dont understand what's a big idea to query SQL from VFP? We should use SP anyway and that SP will use new XML syntax.

If you had a Yukon XML data type map to a VFP cusrsor char memo field, you would not be able to use XQuery to query the XML like you will be able to with Yukon, but you could have a UDF in a VFP SELECT statement that parsed the XML and used XPath but the performance would not be good. The best solution for Yukon XML data types with VFP is to use a stored procedure that executed the SELECT with the XQuery on the server side and then returned the results to VFP in a cursor.
