Renaming a table in Oracle is simple. Following is the generic Oracle table rename syntax:

1

ALTER TABLE current_table_name RENAME TO new_table_name;

In practice, you might realize you left off a prefix that you are using as a naming standard. Changing the table name can be accomplished with the following example syntax:

1

ALTER TABLE employee RENAME TO dw_employee;

If the table is already in use, I recommend that you review custom code, Oracle packages, stored procedures, and any other references to the table. You can use tools like TOAD to view dependencies on the table prior to renaming it. Below is a screenshot within TOAD of the “Used By” tab that can be used when your table is selected in the schema browser:
