Since the mysql client is not a Stored Procedure, the results cannot be manipulated the mysql client level via DML other than doing a SELECT to see the results. This is an awkward solution b, and -- because the temporary table has scope throughout the entire session -- it creates many of the same maintainability issues raised by the use of global variables
The locally managed tempfile is a new feature in Oracle8i to avoid recursive space management operations, which can occur in dictionary managed tablespaces. How to split Export or standard output into smaller pieces ? If you want to export the whole oracle database, or create a TAR archive of one of your filesystem, you may reach a filesize which is bigger than 2 GB
