Introduction to SQL Server Express Edition
SQL Server Express is a free edition of Microsoft’s database server, providing a lightweight version with limited features. It’s ideal for small applications, development environments, or testing purposes where the full functionality of SQL Server isn’t required. With support from versions 2016 through 2022, users have access to various editions like Core and Advanced, as well as LocalDB.
Downloading SQL Server Express
For those looking to download SQL Server Express for versions ranging from 2016 to 2022, there are multiple approaches you can take:
Web Installer
The most common method is using the web installer. This installer allows users to download the necessary files during installation. When launching the web installer, an option to download media (the full installation package) will appear. You can choose between different editions and languages, making it a versatile choice for various needs.
Offline Installers
If you require offline access or need to install SQL Server on a network without internet connectivity, offline installers are available:
-
SQL Server 2019 Express:
- Core: ~249 MB
- Advanced: ~790 MB
- LocalDB: ~53 MB
-
SQL Server 2017 Express:
- Core: ~275 MB
- Advanced: ~710 MB

These files can be downloaded from Microsoft’s official site and used to install SQL Server without an internet connection.
Using Fiddler for Older Versions
For versions where the full installer isn’t readily available through direct links, tools like Fiddler can help. By capturing network traffic during a web installation process, you can determine file URLs that can be accessed directly for offline installations.
