Changes the name of the module being altered. See the RENAME for further discussion. If the new name is the name of a synonym then an error will be raised. The RENAME TO clause requires synonyms be enabled for this database. Refer to the ALTER DATABASE SYNONYMS ARE ENABLED clause. Note that these synonyms may be deleted if they are no longer used by database definitions or applications. The old name will be used to create a synonym for the new name of this module. This synonym can be dropped if the name is no longer used by applications.
