RENAME TABLE allows you to rename an existing table in any schema (except the schema SYS).
RENAME TABLE table-Name TO new-Table-Name
If there is a view or foreign key that references the table, attempts to rename it will generate an error. In addition, if there are any check constraints or triggers on the table, attempts to rename it will also generate an error.
RENAME TABLE SAMP.EMP_ACT TO EMPLOYEE_ACT
Also see ALTER TABLE statement for more information.
If there is an index defined on the table, the table can be renamed.
RENAME TABLE is not allowed if there are any open cursors that reference the table being altered.
