When you use a view with NODATA (or NoDataOnLoad in the data environment) VFP sends a request similar to this to SQL Server:

SET FTMONLY ON 
select myfields from mytable
SET FMTONLY OFF

SET FTMONLY is a SQL Server command.

You can use SQL Server profiler to see this. Just fire SQL Server profiler, then go to VFP's command window and open a view with NODATA. Then, go to the profiler and see what VFP sent to SQL Server.
