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.

Track coding information


Once the development stage of the code base is over, it might be required to track through the code for search operation or to extract some crucial information for analysis or maintenance purposes. Such scenarios do not require thorough line-by-line digging as might seem to be the case. The line-by-line or code-by-code approach not only eats up a lot of time and resource but also ends up in a huge effort with tiny result. For this reason, Oracle supplies a set of dictionary views which make the life of analysts easy. The Oracle-supplied dictionary views are proven metadata sources of Oracle to provide accurate and detailed end results. The dictionary views used for tracking PL/SQL code information are ALL_ARGUMENTS, ALL_OBJECTS, ALL_SOURCE, ALL_PROCEDURES, and ALL_DEPENDENCIES.

The following diagram lists the dictionary views along with a brief description. Note that only ALL_* views are listed in the chart but, nevertheless, the same purpose is achieved by the other...
