I learned a lot from the SQLite documentation. It's not only very thorough, but it's full of insightful bits of information that is not strictly necessary but which gives a deeper understanding of the engine.

It was also the first time I encountered the flow diagram type of syntax explanation which I found to be a fantastic way to grasp the details of each command. Eg https://sqlite.org/lang_createtable.html.
