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.

Extended events


As with all new features inside SQL Server, In-Memory OLTP also provides Extended Events session details. There is an extensive set of events that can be captured by Extended Events. Using the Extended Events Wizard will allow you to easily choose which events you wish to collect. Extended Events is the preferred method for collecting internal system information on any feature of SQL Server (where possible). Extended Events is a lightweight collection framework that allows you to collect system runtime statistics while keeping resource usage to a minimum.

A T-SQL query to return a list of the Extended Events that are available for the In-Memory OLTP engine would be:

SELECT p.name, 
    o.name, 
    o.description 
FROM sys.dm_xe_objects o 
    JOIN sys.dm_xe_packages p 
        ON o.package_guid = p.guid 
WHERE p.name = 'XtpEngine';
