That's what I do at $dayjob whenever I have to do windowing &c. Figuring out this stuff in Pandas is a waste of time. Before I discovered DuckDB, I would re-learn the API every damn time.
I came up with a little utility function, which you can implement yourself :)
Years of unpicking others use of Rs sqldf (which by default used to copy the entire data frame to a SQLite db, run the query, the copy the result set back) when they complained their R code was to slow has taught me a visceral, negative to the name and pattern.
Glad to to see duckDB delivering, finally, on the promise of running SQL against in-memory dataframes
