SQL Server 2017 Developer???s Guide

Overview of this book

Microsoft SQL Server 2017 is a milestone in Microsoft's data platform timeline, as it brings in the power of R and Python for machine learning and containerization-based deployment on Windows and Linux. This book prepares you for advanced topics by starting with a quick introduction to SQL Server 2017's new features. Then, it introduces you to enhancements in the Transact-SQL language and new database engine capabilities before switching to a different technology: JSON support. You will take a look at the security enhancements and temporal tables. Furthermore, the book focuses on implementing advanced topics, including Query Store, columnstore indexes, and In-Memory OLTP. Toward the end of the book, you'll be introduced to R and how to use the R language with Transact-SQL for data exploration and analysis. You'll also learn to integrate Python code into SQL Server and graph database implementations as well as the deployment options on Linux and SQL Server in containers for development and testing. By the end of this book, you will be armed to design efficient, high-performance database applications without any hassle.

The request is still open, as you can see in the following screenshot, and you will see later in this chapter, why it still makes sense to have it in the active state:

Highly ranked requests for SQL Server on the Microsoft Connect site (October 2017)

What arguments are used by community members to justify the request? They are as follows:

  • JSON is already standard, and it should be supported, similar to XML.
  • Other vendors support it (Oracle, PostgreSQL, and others)
  • Due to the lack of JSON support, my customers want to move from SQL Server to other database systems supporting JSON.

As always with vox populi (the opinions or beliefs of the majority), some of the arguments and given examples represent development...
