If you absolutely need a single .exe or a folder you can carry on a USB stick, the community has solved this problem.
The most popular solution is "SQL Server Express by PortableApps" (often found on sites like PortableApps.com or via specific developer GitHub repos).
How it works: These wrappers install a minimal instance of SQL Server into a specific folder. When you launch the "Portable" executable, a launcher script silently installs the necessary services into the Windows Temp folder, starts them, and allows you to use the database. When you close the application, the script stops the services and removes them.
Pros:
Cons:
Yes, but Docker itself requires installation. Using mcr.microsoft.com/mssql/server:2019-latest on Docker Desktop gives you isolation, but it’s heavier than LocalDB.
Before you decide to run your database off a USB 3.0 drive, consider the trade-offs.
To understand the limitations, you must first understand how SQL Server operates.
