COPY
----
This option is the simplest one for changing the ownership of a table. To use it, you must have SQL*Net configured in your system. For syntax details, see the SQL*Plus User's Guide and Reference. With the COPY command, the storage parameters of the table cannot be changed. The table will be recreated in the default tablespace of the user to whose schema the copy is made. For example, to copy table EMP belonging to SCOTT into JOE's schema, the statement is:
COPY FROM scott/tiger@ny to joe/lion@ny CREATE JOE_EMP USING SELECT * FROM EMP
