Nested loops join Nested loop involves an index on at least one of the table. In this case a full table scan is done on one table. For every row found a lookup is performed on the second table usually the one which is indexed In a hash join, a hash table is constructed for the larger table.
The smaller table is then scanned and the hash table is then used to find matching rows in the larger table Using Join Techniques Use nested loops when only a small subset of the rows needs to be accessed and an index is available to support it. Use sort and hash merge if joining most or all rows of the tables. When determining the best join order try to start with the table which will return the smallest number of rows, providing that the subsequent tables can be joined efficiently.
The optimizer sometimes automatically translates IN-based subqueries into a join. However Oracle has some special optimization for it. Avoid over indexing, specially for columns which are frequently updated. Use array inserts. Avoid arithmetic calculations in SQL. Perform this work in the program code. Optimizing DML 2 of 4 Retrieve only the columns necessary. Specify the fields in an insert statement, even if all fields are inserted. Always try to use joins instead of sub-queries within queries.
This is a valuable reference for anyone who works on Oracle Performance Tuning. With a master like Rich on your bookshelf, you can aim high with confidence. Rich has done an Ace job with it.
It is well written, easy to read, and full of practical tips. Novices and experienced DBAs as well as developers will find this book invaluable. Even veteran DBAs will find this book difficult to put down.
Through hard work and determination he overcame obstacles and serves as a role model for all students in TRiO Pre-College Programs.

His knowledge and passion go beyond computers; he seeks to inspire others to have the courage to make their dreams come true, too! And then there was Rich. Years later, Rich is still a beacon whose insights light the path to my own discovery. The proven techniques Rich explains in this book will help you create the most efficient applications possible. Every developer who works with the Oracle database should own and read this book. This book will be like a dictionary for DBAs facing critical problems.
I have followed thoroughly all his books on tuning from 8i and found them the ultimate for Oracle Performance Tuning going into the minutest details. His unique techniques and methods have not only positively influenced me but also many other Oracle professionals.
This book is the ultimate for Oracle 10gR2 Tuning! The examples connect the dots and bridge the gap of theoretical academics to the real world. Robinson, Jr. He consistently contributes his time, knowledge, and professional experience with the Oracle user community by introducing new features or helping others in need of support.
Niemiec are a unique experience within tuning issues. He not only masters the theory and tools but is also able to perform insightful analyses of real-world problems and present the results in a way that makes sense even to people not so experienced with database technologies. This is important since business people are getting more and more interested in IT performance in general—as they really should.
Rich exposes the complexities of tuning to satisfy the passionate beginner and the seasoned professional. Packed with real-world examples, interesting dialogue, and deep technical content—this is the best tuning book on the market.
The meeting between Richard and myself in Chicago nine years later convinced me that he is in the forefront of this technology—a leader. The book shows the fact that he is always on the leading edge of this technology.

A partner in life is finer than gold, more pleasing than success, sweeter than any words. Greater than gold is this beautiful rose. Greater than success is the path on the road less traveled. Greater than praise is lasting character. Gold glistens, but is of little refuge on a cold Chicago night. Success is enticing, but its promises ring empty without the right person to share it with. Praise is shallow unless it comes from the person who matters most to you. The world offers many outwardly shiny things that prove hollow on the inside.
A partner gives you the strength to be successful when you want to give up. For me that person was always and is always Regina! She is worth more to me than the world can ever offer.
Yet she makes me a better person, and I achieve everything that I can offer the world. Surely my cup overflowed the day I met her!
Regina is that one person in the world who completes me. Regina is still the greatest person I know in the world. I am one of the lucky ones in the world; my partner in life is right by my side. I love you, Regina, with all my heart! Thanks for your love, energy, fun, and care. You are each incredible in your own way.
In your eyes, I see the love of God shine into the world and into my life. He has blessed me greatly. Installation Improvements. Automatic Storage Management. Server-Generated Alerts.
