That's actually not a bad idea, to have LLM autocomplete when you write queries, especially if you first add a comment at the top saying what you want to achieve:

// Select all orders for users registered in last year, and compute average earnings per user

SELECT ...

That already works in windsurf, I’ve created unit tests in go, where I just wrote a short comment in the unit test what data to query and windsurf would autocomplete with the full sql.

I mean, all LLMs do this already, but I never saw LLM autocomplete in a db tool (e.g. phpmyamdin, MongoDB Compass, etc).

Vibe SQLing is where it's at
