If both servers are on the same network with reasonable connection speed, - create target_table nologging as select * from [EMAIL PROTECTED]
will beat all other options as it creates the table in one step - no writing/transfering/reading intermediate files in between, and nologging uses the same direct-path functionality as SQL*Loader. Simple enough to whip out the stopwatch and test whether it applies in your case or not. ----- Original Message ----- To: "Multiple recipients of list ORACLE-L" <[EMAIL PROTECTED]> Sent: Tuesday, August 26, 2003 8:04 AM > Thanks Tanel > We will undoubtedly use export/import for the many small tables.
