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.

Introduction to SQL Server 2017

Enabling and configuring Query Store


As with all new features, Query Store is not active for a database by default. You can enable and configure it in SQL Server Management Studio (SSMS) by using the database properties (Query Store page) or by using Transact-SQL. To enable Query Store, your account must be the db_owner of the database or a member of the sysadmin fixed server role.

Enabling Query Store with SSMS

To enable Query Store for a database, you need to select it and click on Properties. You can find a new Query Store property page at the bottom of the list. As mentioned at the beginning of the section, it is disabled by default, which is indicated by the values Off for both Operation Mode (Actual) and Operation Mode (Requested). To enable it, you need to change the value for the parameter Operation Mode (Requested) to Read Write, as shown in the following screenshot:
