Prepare to Copy a Database Object
Before you copy a database object, check whether the user already owns an object by the same name in the new database.
In the case of a table, it must be destroyed before proceeding.
Caution! If you fail to do this, the new table cannot be successfully created, and you can potentially populate the existing table with unwanted data.
For other user objects (forms, reports, and applications) be aware that the object being moved can replace an object with the same name in the new database.
