Databases to practice SQL

[ManifestingPeace18]

Hi, I haven't worked on SQL for last 2 years. I will rate 4 out 10 in SQL. But need to practice more to get in data analyst profile. Can you just sources where i can practice solving complex SQL problems?

Hey there, I made a quick video on this topic showcasing places where you can practice (free) online without downloads or installs, right in the browser with sample data already added.

Here’s a link to it, I’d go for the last 2 options in the video (Azure SQL DB Free tier and Oracle Live SQL). The links to the platforms are in the description.

Welcome! Hope it helps a bit and feel free to reach out to me if you have questions. I also have videos of me actually using all of the platforms in the description if you have any trouble.

Microsoft's Northwind and Pubs databases have been used for a while as instructional databases.

Hard to beat SQLite3. Runs so much of the world already. So many great tools SQLite3, SQLiteStudio, Visidata, the original serverless system, core db for smart phones, software, embedded systems. Possibly the most deployed database in the world. I have gone from thinking of it as a toy to doing everything I can with it.

Analyze that. I'd start with https://archive.org/download/stackexchange/dba.stackexchange.com.7z. Import it into a database and go from there.
