Throughout this series, procedures have been used to break programming problems into collections of interlinked but self-contained modules. This chapter seeks to examine the different means of interlinking such modules and thereby to analyze the different roles which they play in modular program design...

If you include your procedures and functions in a separate program file, you can make these procedures and functions accessible in your program by using the SET PROCEDURE TO command. For example, for a file called FUNPROC.PRG, use this command in the Command window: Copy SET PROCEDURE TO ...
This chapter describes the main types of program units you can create with PL/SQL: procedures, functions, and packages. Procedures, functions, and packages are saved and stored in the database, and can be used as building blocks for applications. For information about the features of the PL/...
In the chapter on PL/SQL, you saw how powerful and useful this programming language could be. I’m sure any developers reading it also noticed that it was a little limiting though. All there seemed to be were anonymous (unnamed), self-contained blocks of
Invoking functions/procedures inside functions/procedures Getting started 1. Creating a hello world in a stored procedure in SQL vs a function Let’s create a simple “Hello world” in a stored procedure and a function to verify which one is easier to create. We will first create a simple...

System Functions The idea behind functions is to store them in the database and avoid writing the same code repeatedly. Let us concentrate on the first two functions. Create a Scalar-valued Function to Add Two Integers CREATE or ALTER FUNCTION dbo.udfGetSum(@NumA int, @NumB int) ...
If you plan to call a stored procedure using a stub generated by SQL*Module, then the stored procedure name must also be a legal identifier in the calling host 3GL language, such as Ada or C. Parameters for Procedures and Functions
