SQL Server Express Edition (Free Version Of SQL Server)
SQL Server Express Edition is a free, feature-rich edition of SQL Server designed primarily for learning, developing, and powering desktop, web, and small server applications, as well as for redistribution by ISVs. Ideal for hobbyists, developers, and students, SQL Server Express provides many of the core features of SQL Server. Still, it has limitations in database size and resources to make it suitable for smaller applications and environments where cost is a critical factor.
The Express Edition offers a great way to start with SQL Server without the financial investment required for the full versions. It supports advanced features such as full-text search, database snapshots, and some of the high availability mechanisms, albeit with restrictions that reflect its positioning as an entry-level option.
For those interested in downloading SQL Server 2019 Express Edition or the latest version of SQL Server 2022 Express Edition, Microsoft provides these versions through their official website. The following links direct you to the download pages:
SQL Server 2019 Express Edition:
You can download this version from Microsoft's official download page at https://www.microsoft.com/en-gb/download/details.aspx?id=101064.
SQL Server 2022 Express Edition:
This newer version can also be found on Microsoft's SQL Server downloads page at https://www.microsoft.com/en-us/sql-server/sql-server-downloads.
Key Features of SQL Server Express Edition:
Free version: It is a free edition of SQL Server, making several components and more advanced features suitable for developers and small businesses without incurring licensing costs.
Distribution: It can be freely redistributed with applications, which makes it an attractive option for independent software vendors and developers who need a cost-effective way to bundle a robust choice, reliable database system with their applications.
LocalDB: SQL Server Express includes a lightweight version called LocalDB which is specifically designed for developers. It is easy to install and has fewer prerequisites, making it ideal for building and testing applications.
Limitations of SQL Server Express Edition:
Compute Capacity: It is limited to the lesser of 1 socket or 4 cores. This limitation restricts the computing power available to the database engine, affecting the performance of more demanding applications.
Memory: SQL Server Express can only use a maximum of 1GB of memory for the database engine process. This could be a bottleneck for applications requiring more memory-intensive database operations.
Maximum Database Size: Each database can hold a maximum of 10GB. This limitation may not be suitable for applications with large data storage needs.
High Availability: Features like failover clustering support are unavailable in the Express edition right version, limiting the options for increasing application uptime through SQL Server technologies.
SQL Agent: SQL Server Express lacks the SQL Agent feature, meaning it cannot schedule jobs such as backups or automated tasks directly through the SQL Server agent. This could necessitate manual intervention or external scheduling mechanisms for routine database maintenance tasks.
Use Cases for SQL Server Express Edition:
Given its limitations, SQL Server Express is best suited for:
Development and testing environments where the test database, size, and performance demands are within the constraints of the Express edition.
Small applications and websites with a limited number of users do not require high levels of concurrency or large data storage.
For educational learning purposes, only, this is a powerful tool for students and new developers to learn SQL Server without needing to invest in full versions.
For scenarios with small server applications that outgrow SQL Server Express's capabilities, upgrading to a more robust enterprise edition of SQL Server that removes these limitations would be necessary.

SQL Developer Edition
The key aspect of the Developer Edition is that while it's fully featured, the license limits its use to development and testing scenarios only. It cannot host live databases in a production environment. This makes it a fantastic resource for learning and experimenting with the various features and capabilities of SQL Server, including advanced data integration, data warehousing, and business intelligence features.
As of the latest information available for today's date, March 9, 2024, you can download the SQL Server Developer Edition directly from Microsoft's official SQL Server downloads page:
SQL Server 2022 Developer Edition:
You can initiate the download process by visiting the official SQL Server downloads page at https://www.microsoft.com/en-us/sql-server/sql-server-downloads. This page provides access to the latest version of SQL Server Developer Edition, along with instructions for installation and setup.
SQL Server 2019 Developer Edition: (Full Featured free edition)
Although the focus might be on the latest version, SQL Server 2019 Developer Edition is also available and can be downloaded following steps similar to those of the 2022 version. The direct download link provided through community resources like Stack Exchange (https://dba.stackexchange.com/questions/322065/how-do-i-download-sql-server-2019-developer-edition) points to Microsoft's unified download page, indicating that Microsoft centralizes its download resources.
Features of SQL Server Developer Edition:
Full Functionality:
It includes all the features available in SQL Server Enterprise Edition. This means developers have access to advanced features, such as SQL Server Data Tools, advanced security features, data warehousing, and business intelligence capabilities, which can be crucial for developing complex applications (Microsoft Docs).
Integrated Testing and Development Environment:
Developers can benefit from an integrated environment that supports testing and development, making it easier to simulate real-world scenarios and ensure the application performs well under various conditions (Softtrader.eu).
Support for Multi-Platform Deployment:
The Developer Edition supports deployment across different platforms, which is key for building applications that need to operate in diverse environments.
Limitations of SQL Server Developer Edition:
Licensing for Development Only:
While offering full functionality, the Developer Edition is strictly licensed for development and testing purposes. It cannot be used in a production environment. This limitation means that while you can build and test your applications using all of SQL Server's features, you need to purchase a suitable license for non production environment and use (SQLShack).
No Direct Production Support:
Given its designation for development and test environments, applications running on SQL Server Developer Edition do not have direct support for production issues. For production-level support, a different edition of SQL Server that includes production support would be required.
The SQL Server Developer Edition is an excellent tool for developers looking to leverage all the features and full capabilities of the SQL Server environment without incurring upfront costs. Its provision of all the features and complete feature set of the Enterprise Edition for development purposes makes it an invaluable resource for developing, testing, and demonstrating applications.
However, businesses must ensure they transition to a properly licensed SQL Server edition before moving their applications from a nonproduction environment into a production environment.
Should I use the Azure SQL version or download SQL Server on-premises?
Can I use cloud services to do anything else? When switching to cloud storage, it is not necessary to download and install SQL Server. You will only need SSMS to establish the connection and run your databases on cloud platforms. You may download the Microsoft SSMS program at this URL. If you download SSMS from a web browser, it is necessary. Previously, this was part of the full installation instructions for Microsoft SQL servers.
