SQL Server editions

The following table describes the editions of SQL Server.

1 Unlimited virtualization is available on Enterprise edition for customers with Software Assurance. Deployments must comply with the licensing guide. For more information, see our pricing and licensing page.

Use SQL Server with client/server applications

You can install just the SQL Server client components on a computer that is running client/server applications that connect directly to an instance of SQL Server. A client components installation is also a good option if you administer an instance of SQL Server on a database server, or if you plan to develop SQL Server applications.

SQL Server components

SQL Server 2022 (16.x) on Linux supports the SQL Server Database Engine. The following table describes the features in the Database Engine.

Server components	Description
SQL Server Database Engine	SQL Server Database Engine includes the Database Engine, the core service for storing, processing, and securing data, replication, Full-Text Search, tools for managing relational and XML data, and in database analytics integration.

Developer, Enterprise Core, and Evaluation editions
For features supported by Developer, Enterprise Core, and Evaluation editions, see features listed for the SQL Server Enterprise edition in the following tables.

The Developer edition continues to support only one client for SQL Server Distributed Replay.
