Pro Oracle SQL unlocks the power of SQL in the Oracle Database—one of the most potent SQL implementations on the market today. To master it requires a three-pronged approach: learn the language features, learn the supporting features that Oracle provides to help use the language effectively, and learn to think and work in sets., , Karen Morton and her team help you master powerful aspects of Oracle SQL not found in competing databases. You’ll learn analytic functions, the MODEL clause, and advanced grouping syntax—techniques that will help in creating good queries for reporting and business intelligence applications. Pro Oracle SQL also helps you minimize parsing overhead, read execution plans, test for correct results, and exert control over SQL execution in your database. You’ll learn when to create indexes, how to verify that they make a difference, how to use SQL Profiles to optimize SQL in packaged applications, and much more. You’ll also understand how SQL is optimized for working in sets, and that the key to getting accurate results lies in making sure that queries ask clear and precise questions., , What’s the bottom-line? Pro Oracle SQL helps you work at a truly professional level in Oracle dialect of SQL. You’ll master the language, the tools to work effectively with the language, and the right way to think about a problem in SQL. Pro Oracle SQL helps you rise above the crowd to provide stellar service in your chosen profession. Endorsed by the OakTable Network, a group of Oracle technologists well-known for their rigorous and scientific approach to Oracle Database performance Comprehensive – goes beyond the language with a focus on what you need to know to write successful queries and data manipulation statements. What you'll learn Master powerful SQL features implemented only in Oracle Database Read and interpret SQL execution plans Quickly diagnose and fix badly performing SQL Control execution plans through hints, profiles, and plan baselines Optimize queries within packaged applications without touching the code Recognize when not to waste time on SQL that is performing optimally Who this book is for Pro Oracle SQL is aimed at developers and database administrators who submit SQL for execution by an Oracle database. Readers should already know the basic four SQL statements, and be ready to learn deeply about Oracle’s specific implementation of the language, including Oracle-specific features and syntax. Readers should also want to learn about Oracle Database features such as analytic queries, the MODEL clause, and subquery refactoring that are designed to help developers and DBAs exert control over their SQL environment and its execution.

Since this book is only a couple of hundred pages and the 11g manuals extend to tens of thousands of pages it seems unlikely that I could possibly be describing “the whole thing ” so let me qualify the claim The book is about the core mechanics of the central database engine the bit thatdrives everything else; essentially it boils down to undo redo data caching and shared SQL Even then I’ve had to be ruthless in eliminating lots of detail and interesting special cases that would make the book too long turgid and unreadable Consider for example the simple question: How does Oracle do a logical I O then take a look at structure x$kcbsw which is a list of all the functions that Oracle might call to visit a block You will find for 11 2 0 2 that there are 1 164 different functions for doing a logical I O do you really want a detailed breakdown of all the options or would a generic description of the common requirements be sufficient ">Since this book is only a couple of hundred pages and the 11g manuals extend to tens of thousands of pages it seems unlikely that I could possibly be describing “the whole thing ” so let me qualify the claim The book is about the core mechanics of the central database engine the bit thatdr [更多]

Oracle学习资源，对于初学者是个不错的帮助资料。

This book is designed to be read from beginning to end by those new to
PL/SQL. Part I covers PL/SQL fundamentals. Part II covers the backbone
of the programming language, which consists of functions, procedures,
packages, triggers, and large objects. Part III dives into some advanced
topics that should help you immediately with your development projects.
The appendixes in Part IV provide primers on Oracle DBA tasks, SQL programming,
PHP scripting, Java development, regular expressions, and wrapping PL/SQL. Introductory
primers are provided to help you learn about the PL/SQL Hierarchical Profiler and PL/Scope.
There is also an appendix that reviews reserved words and built-in functions that support
your programming tasks.
