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

Row-Level Security 


In the first part of this chapter, you learned about permissions on database objects, including objects with data, namely tables, views, and table-valued, user-defined functions. Sometimes you need to give permissions to end users in a more granular way. For example, you might need to give permissions to a specific user to read and update only a subset of columns in the table, and to see only a subset of rows in a table.

You can use programmable objects, such as stored procedures, to achieve these granular permission needs. You can use declarative permissions with DCL statements (GRANT, REVOKE, and DENY) on the column level already available in previous versions of SQL Server. However, SQL Server 2016 and 2017 also offer declarative Row-Level Security, abbreviated to RLS. In this section, you will learn how to:

  • Use programmable objects to maintain security
  • Use SQL Server 2016 and 2017 RLS
