The overloaded calling name of the function is to be renamed.

function_name
Existing overloaded calling name of the function to be changed.
You cannot rename a table operator function. For more information, see “Table Operators” in “C/C++ User-Defined Functions” and “Java User-Defined Functions” of Teradata Vantage™ SQL External Routine Programming , B035-1147 .
If the UDF library for your database contains any objects with multibyte characters in the name, you cannot use a single-byte session character set to create a new UDF, UDT, method, or Java stored procedure object even if the new object name contains only single-byte characters. Otherwise, Teradata Database returns an error to the requestor. Instead, use a multibyte session character set.
If you specify function_name, then you must also specify new_function_name, not new_specific_function_name.

Containing database for function_name if something other than the current database.
user_name
Containing user for function_name if something other than the current user.
