BOOK DESCRIPTION
SQL has been the de facto standard when interacting with databases for
decades and shows no signs of going away. Through the years, report
developers or data wranglers have had to learn SQL on the fly to meet
the business needs, so if you are someone who needs to write queries,
SQL Query Design and Pattern Best Practices is for you. This book will
guide you through making efficient SQL queries by reducing set sizes
for effective results. You’ll learn how to format your results to
make them easier to consume at their destination. From there, the book
will take you through solving complex business problems using more
advanced techniques, such as common table expressions and window
functions, and advance to uncovering issues resulting from security in
the underlying dataset. Armed with this knowledge, you’ll have a
foundation for building queries and be ready to shift focus to using
tools, such as query plans and indexes, to optimize those queries. The
book will go over the modern data estate, which includes data lakes
and JSON data, and wrap up with a brief on how to use Jupyter
notebooks in your SQL journey. By the end of this SQL book, you’ll
be able to make efficient SQL queries that will improve your report
writing and the overall SQL experience.
