- You cannot rename a table operator function, that is, a function with a parameter style of SQLTABLE. For more information, see the information about table operators for C/C++ and Java user-defined functions in Teradata Vantage™ - SQL External Routine Programming, B035-1147.
If the UDF library for your database contains any objects with multibyte characters in their 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, Vantage returns an error to the requestor. Instead, use a multibyte session character set.
- If you specify specific_function_name, then you must also specify new_specific_function_name, not new_function_name.
- new_specific_function_name
- New specific function name for the function.
