You know the rudiments of the SQL query language, yet you feel
you aren't taking full advantage of SQL's expressive power.
You'd like to learn how to do more work with SQL inside the
database before pushing data across the network to your
applications. You'd like to take your SQL skills to the next
Let's face it, SQL is a deceptively simple language to learn,
and many database developers never go far beyond the simple
statement: SELECT FROM
WHERE .
But there is so much more you can do with the language. In the
SQL Cookbook, experienced SQL developer Anthony Molinaro
shares his favorite SQL techniques and features. You'll learn
- Window functions, arguably the most significant enhancement
to SQL in the past decade. If you're not using these, you're
- Powerful, database-specific features such as SQL Server's
PIVOT and UNPIVOT operators, Oracle's MODEL clause, and
- Pivoting rows into columns, reverse-pivoting columns into
rows, using pivoting to facilitate inter-row calculations, and
- Bucketization, and why you should never use that term in
- How to create histograms, summarize data into buckets,
perform aggregations over a moving range of values, generate
running-totals and subtotals, and other advanced, data
- The technique of walking a string, which allows you to use
SQL to parse through the characters, words, or delimited
Written in O'Reilly's popular Problem/Solution/Discussion
style, the SQL Cookbook is sure to please. Anthony's credo is:
"When it comes down to it, we all go to work, we all have
bills to pay, and we all want to go home at a reasonable time
and enjoy what's still available of our days." The SQL
Cookbook moves quickly from problem to solution, saving you
time each step of the way.
