16.20 - SPECIFIC METHOD - Teradata Database - Teradata Vantage NewSQL Engine

This clause is mandatory for overloaded method_names, but is otherwise optional and can only be specified once per method definition.

specific_method_name

Specific name for the method.

For information about naming database objects, see Teradata Vantage™ SQL Fundamentals, B035-1141.

This name is stored in DBC.TVM as the name of the method database object.

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, or method, 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.

SYSUDTLIB

Unlike method_name, specific_method_name must be unique within SYSUDTLIB.

Example: Replacing a Method Definition Using Its Specific Method Name

The following example replaces the existing method with the specific method name polygon_mbr with a new definition.

     REPLACE SPECIFIC METHOD SYSUDTLIB.polygon_mbr
     EXTERNAL 'CO!C:\sys\spatial.lib!CO!C:\udt_lib\polymbr.obj!F!toUS'
