SQL
Tuning by Dan. Tow

A poorly
performing database application not only costs users time, but
also has an impact on other applications running on the same
computer or the same network.

SQL
Tuning provides an essential next step for
SQL developers and database administrators
who want to extend their SQL tuning
expertise and get the most from their database applications.


There are two basic issues to focus on when
tuning SQL: how to find and interpret
the execution plan of an SQL statement
and how to change SQL to get a specific
alternate execution plan. SQL Tuning
provides answers to these questions and addresses a third
issue that's even more important: how to find the optimal
execution plan for the query to use.

Author
Dan Tow outlines a timesaving method
he's developed for finding the optimum execution plan--rapidly
and systematically--regardless of the complexity of the
SQL or the database platform being used.
You'll learn how to understand and control
SQL execution plans and how to diagram
SQL queries to deduce the best execution plan
for a query. Key chapters in the book include exercises to
reinforce the concepts you've learned. SQL
Tuning concludes by addressing special concerns and
unique solutions to "unsolvable
problems"

Whether you are a
programmer who develops SQL-based
applications or a database administrator or other who
troubleshoots poorly tuned applications, SQL
Tuning will arm you with a reliable and deterministic
method for tuning your SQL queries to
gain optimal performance.
