The answers may vary on this one. I don't think there is much difference speedwise, though you might get a slight advantage when using passthrough to retrieve data.

>which method gives better batch update performance ?
It will be nearly the same but views will provide more flexibility for manupulating data. If you are looking for large batch updates consider looking at BCP.

>if i send a query through SQL pass through does the SQL syntax have to be in the server's SQL syntax or in VFP SQL-Select syntax ?
Server's

Yes. Its very similar though but you could do a lot more with SQL Server.
