@chekunkov Is %s in an SQL query a good idea? Anki supports parameterised queries so you can use ? instead of %s then provide the thing you are providing to % as another argument to the self.col.db.execute function. It doesn't seem too bad in this case because it's client side and the only thing the user can destroy is their own stuff and it's using the result from an Anki function, but it's still best to provide good examples to new programmers.

@wizzwizz4 parameterised queries are not useful here. they'd quote the set. ids2str makes sure only integers are passed anyway, so your concerns aren't valid.
