Hence read only shared access is not desirable. Should we try using the SQL Create Table and then SQL Insert to build a sharable Temp Table.

If you really need in temporary shared DBF you can use EITHER Select-SQL and then Use, Use..Shared OR Create Table and then INSERT-SQL. Also you can use COPY TO and probably many other XBASE commands.
