What Is a Procedure?

Submitted by: Administrator

A procedure is a named program unit. It consists of three parts:

► Declaration Part - Defining the procedure name, calling parameters, local variables and local procedures. Declaration part is required.
► Execution Part - Defining execution logic with executable statements. Execution part is required.
► Exception Part - Defining error handling logics. Exception part is optional.

Here how a complete procedure should look like:

PROCEDURE name (parameter_1, parameter_2) AS
-- Declaration statements
BEGIN
-- Executable statements
EXCEPTION

END;
