Slide 14.12: Oracle methods

Oracle Methods

Methods are user-defined functions that are defined along with a user-defined type.

A method is a procedure or function that is part of the object type definition.

^†Because they are included in the type, they are called MEMBER methods of the type.

Are implemented in PL/SQL or a host language, such as C, stored externally.
An external procedure is a procedure implemented in a language not stored in the database but callable from SQL. After the procedure is implemented, the compiled code must be placed in a file accessible to the database server. Then the external procedure is registered with the server using a CREATE PROCEDURE or CREATE FUNCTION statement.

^†It requires a DBA privilege to use an external procedure.
