You develop the body of a UDF using the Java programming language. The source can be on the client system or on the database server.

You can use any class name or method name to implement the Java UDF. Later, when you use the CREATE FUNCTION or REPLACE FUNCTION statement to create an SQL identifier for the UDF, you specify the class and method names so that Teradata Database knows what to execute when an SQL statement specifies the UDF.
