Idea: import CSV to memory, run SQL, export in a single command

I quite often load a CSV file into a SQLite DB, then do stuff with it (like export results back out again as a new CSV) without any intention of keeping the CSV file around afterwards.

What if sqlite-utils could do this for me? Something like this:

sqlite-utils --csv blah.csv --csv baz.csv "select * from blah join baz ..."

Solution: sqlite-utils memory - attempts to detect the input based on if it starts with a { or [ (likely JSON) or if it doesn’t use the csv.Sniffer() mechanism. Or you can use sqlite-utils memory -:csv to specifically indicate the type of input.
