Overview of this book

PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension language for SQL and the Oracle relational database. Server-side PL/SQL is stored and compiled in the Oracle Database and runs within the Oracle executable. With this guide Oracle developers can work towards accomplishing Oracle 11g Advanced PL/SQL Professional certification, which is the second milestone for developers working at the Associate level. The Oracle Advanced PL/SQL Developer Professional Guide helps you master advanced PL/SQL concepts. Besides the clear and precise explanation on advanced topics, it also contains example code and demonstrations, which gives a sense of application and usage to readers.The book gives a deep insight that will help transform readers from mid-level programmers to professional database developers. It aims to cover the advanced features of PL/SQL for designing and optimizing PL/SQL code.This book starts with an overview of PL/SQL as the programming database language and outlines the benefits and characteristics of the language. The book then covers the advanced features that include PL/SQL code writing using collections, tuning recommendations using result caching, implementing VPD to enforce row level security, and much more. Apart from programming, the book also dives deep into the usage of the development tool SQL Developer, employing best practices in database environments and safeguarding the vulnerable areas in PL/SQL code to avoid code injection.

Using SQL Developer to find coding information


The object metadata information retrieved from the dictionary views is a conventional way to track code information. But these days, the IDE have been made self-sufficient to generate some vital predefined reports. The metadata information demonstrated in the last section using dictionary views can also be generated from SQL Developer. SQL Developer is a free UI based interactive IDE tool which boards multiple database utilities.

Here, we will demonstrate the tracking of code through SQL Developer:

  1. Go to View | Reports:

  2. Go to All Reports | Data Dictionary Reports | PLSQL:

    • Under PLSQL, you find three options. These options are analogous to the dictionary views which we queried in the preceding section.

    • The Program Unit Arguments option queries the USER_ARGUMENTS dictionary view. The Search Source Code and Unit Line Counts options query the USER_SOURCE view.

    • When you click on any of the options for the first time, the following dialog box pops up...
