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.doi:10.1007/978-3-642-67911-7_7Susan EisenbachChristopher SadlerSpringer ...

Procedures and functions allow you to keep commonly used code in a single place and call it throughout your application whenever you need it. This makes your code easier to read and easier to maintain because a change can be made once in the procedure rather than multiple times in your ...
Subroutines are an important part of anyprogramming language, and Delphiis no exception. In Delphi, there are generally two types of subroutines: a function and a procedure. The usual difference between a function and a procedure is that a function can return a value, and a procedure ...
The function will invoke the HelloWorldprocedure created in the section 1. If we invoke the function, we will have the following message: Msg 557, Level 16, State 2, Line 65 Only functions and some extended stored procedures can be executed from within a function. ...
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) ...

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/...
User-defined Functions User-defined functions are quite similar to functions written in C, Pascal, or modern Fortran and are compiled for speed. Parameters and Return Values Functions have parameters and return values. Parameters can be passed by value or by reference. They can be numbers, string...
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 FunctionsStored procedures and functions can take parameters. The follow...
