Specific name for the function. This clause is mandatory for overloaded function names, but otherwise is optional and can only be specified once per function definition.
For information about naming database objects, see SQL Fundamentals, B035-1141.
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, the system returns an error to the requestor. Instead, use a multibyte session character set.
- If you use specific_function_name to identify the C or C++ function name, take care to follow the identifier naming conventions of the C or C++ languages. The same suggestion applies to the naming conventions of the Java language for Java functions.
- Unlike function_name, the specific name for a function, method, or UDT must be unique within its database to avoid name clashes. This name is stored in DBC.TVM as the name of the UDF database object.
- An optional database name.
- An optional user name.
