Unveiling Less-Known Features of Microsoft SQL Server: Insights for Experts

Microsoft SQL Server, a robust database management system, offers features beyond the standard repertoire. Whether you are a seasoned database administrator (DBA) or a developer, there are several lesser-known features that can significantly enhance your data management and security capabilities. Here, we delve into some hidden gems of Microsoft SQL Server, particularly those that may not be as well-known.

Less-Known Features and Tips for Microsoft SQL Server

Many features in SQL Server are well-documented, but some lesser-known quirks and best practices can make a world of difference in your day-to-day operations. For instance, when working with AlwaysON clusters, the default method of failover should be performed via the GUI rather than using a SQL command. This precaution prevents potential issues and ensures a smooth transition.

Additionally, it's important to note that a forced failover can lead to data loss, and the databases may not automatically come online once the failover is complete. You need to manually bring them online. These tips, while not breaking news, are crucial for maintaining the integrity and reliability of your database environment.

Highlighting Landmark Features of SQL Server 2016

SQL Server 2016, released in 2016, introduced numerous significant features designed to address modern-day data management challenges. Here are seven mission-critical features that are often overlooked by users:

1. Always Encrypted

Always Encrypted is a security feature designed to protect data at rest or in motion. It allows SQL Server to perform operations on encrypted data and ensures that the encryption keys are never exposed to SQL Server. This feature is ideal for applications that require strict data privacy but need to perform complex queries on the encrypted data. Read more in the detailed article on SQL Server Always Encrypted.

2. Dynamic Data Masking

Dynamic Data Masking is a feature that limits the exposure of sensitive data to non-privileged users. It helps prevent unauthorized access by enabling you to control the visibility of sensitive data based on predefined rules. This ensures that users can only see the data they need to see, without compromising the integrity of the data.

3. Native JSON Support

SQL Server 2016 provides native support for JSON, a standardized data exchange format widely used today. This feature allows for seamless import and export of JSON data, making it easier to work with modern web applications that rely on JSON for data exchange. The built-in parsing and storage capabilities of SQL Server 2016 make it an ideal choice for applications that need to integrate JSON data.

4. Row-Level Security

Row-Level Security enables fine-grained access control based on the characteristics of the user executing a query. This feature is particularly useful in large databases where different users may require access to different subsets of data. By defining row-level security policies, you can ensure that each user only sees the data they are authorized to access.

5. Updated T-SQL Features

SQL Server 2016 introduced several updates to Transact-SQL (T-SQL), the language used to interact with SQL Server databases. These updates improve the capabilities and performance of T-SQL, making it easier to write and maintain complex queries. The new features include improvements in data types, table structures, and query optimization techniques.

6. SQL Server Management Studio Enhancements

SQL Server 2016 introduced several enhancements to SQL Server Management Studio (SSMS), the primary management tool for SQL Server. These enhancements include improved query performance, better database maintenance capabilities, and enhanced user interface elements. SSMS now provides a more intuitive and efficient way to manage your SQL Server databases.

7. Developer-Focused Features

For developers, SQL Server 2016 offers several features that enhance productivity and simplify development tasks. These include support for modern programming languages, integration with popular development tools, and improved debugging capabilities. These features make it easier for developers to build, test, and deploy applications that rely on SQL Server.

For more information on these features, refer to the comprehensive articles on Updated New T-SQL Features in SQL Server 2016 and New Features in SSMS for SQL Server 2016.

By leveraging these hidden gems and modern features of Microsoft SQL Server, you can enhance the security, performance, and efficiency of your data management processes. Whether you are a DBA or a developer, there is always something new to discover in the ever-evolving world of SQL Server.
