The External Module Body

The external module body specifies the UDR engine used to execute the external module, and optionally specifies the name of the UDR routine to call (<extname>) and/or a string (<extbody>) with UDR-specific semantics.

Configuration of external modules and UDR engines is not covered further in this Language Reference.Consult the documentation of a specific UDR engine for details.

Stored Procedures

A stored procedure is executable code stored in the database metadata for execution on the server.It can be called by other stored procedures (including itself), functions, triggers and client applications.A procedure that calls itself is known as recursive.
