PL/SQL Stored Code
All the PL/SQL that you have written up to this point has been anonymous blocks that were run as scripts and compiled by the database server at runtime. Now you will begin to use modular code. Modular code is a methodology to build a program from distinct parts (modules), each of which performs a specific function or task toward the final objective of the program. Once modular code is stored on the database server, it becomes a database object, or subprogram, that is available to other program units for repeated execution. In order to save code into the database, the source code needs to be sent to the server so that it can be compiled into p-code and stored in the database. In the first lab, you will learn more about stored code and how to write one type of stored code known as procedures. In the second lab, you will learn about passing parameters into and out of procedures.
