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.

I got this book to help improve my SQL skills, and it was extremely easy to follow along with. I especially liked the examples from chapter 3. It gives a really good place to begin from as you learn to format data. The use of a recurring data set and seeing the different ways you can manipulate it helps you get the concept and have it stick!

One of the most practical books, I’ve read on SQL and Analytics. Strikes the right balance between theory & examples.Plenty of tips on industry standard Design patterns and best practices that come in handy while coding on the fly, whether you’re a Data-pro or an Analytics wizard, you’ll find some new tips & tricks. Great job authors!

I found this book especially useful in SQL beginner to expert journey. It covers useful basic SQL concept like appropriate technique of filtering the data, basic SQL functions then it moves towards expert level as SQL window functions, query optimization for better performance, Impact of Indexing, Introduction of new concept like handling JSON data, data Lake, Jupiter notebooks. I specially mention very well exampled part of this book “The impact of indexes on query performance” page no 154, this part provides a particularly good example of what is the need to including appropriate index, check the fragmentation and factors responsible for decision making of DBAs for rebuild or reorganize the indexes. A good start for SQL basic and advance learning.
