Could you think about support DuckDB?

DuckDB is sqlite-like in-memory OLAP tool

c# Driver

I could support import/export for DuckDB the same way that I do for MySQL and PostgreSQL. The notebook file itself would still need to be SQLite. I'm afraid SQL Notebook is too deeply linked to SQLite to change the internal engine.

You may be interested in https://github.com/timestored/qstudio. qStudio has an integrated DuckDB engine and @ryanhamilton just added an SQL notebook feature to the latest 4.0 release. This is a deeper DuckDB integration than I'd be able to accomplish in SQL Notebook.

Happy that you can support import/export for DuckDB。
For now make SQL Notebook better。
Many thanks
