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.

Ch-Ch-Changes


It's not only the legend that is Mr. David Bowie who sings about changes. In SQL Server 2014, we were destined to create In-Memory OLTP objects that were unchangeable after creation. If we needed to change the structure of a memory-optimized table, we had to resort to dropping and re-creating the object with the new, updated structure.

For many developers and customers, this was a deal breaker. Being able to add and remove columns or indexes is something that every SQL Server developer is used to being able to do without any restriction. With the advent of agile software development and similar development strategies such as continuous integration, being able to make changes to a software application is something many developers look for.

Now it is possible to do just that. We will be continuing this chapter with the same database as in Chapter 11, Introducing SQL Server In-Memory OLTP. We will use the following code to create a simple memory-optimized table, shown as follows...
