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.

Feature improvements


While being able to alter existing objects without having to drop them first is a welcome improvement, many developers are more interested in being able to use data types and T-SQL syntax in the In-Memory OLTP engine that go beyond the basics. In SQL Server 2016 and 2017, we were presented with a great deal of extra support, as is typical with a feature that has matured beyond initial introduction. In this section of the chapter, we will take a look at what areas of the database engine are now supported in the In-Memory OLTP engine.

Collations

The first major addition is the fact that both memory-optimized tables and natively compiled stored procedures support all code pages and collations that SQL Server supports. The previous limitation of only a supporting a subset of collations otherwise available in SQL Server has been completely removed from the product (a newly supported collation has been used in the test table in the demo scripts in this chapter)
