How to bind string for IN clause?
This code doesn't work:
$field_ids = implode(',', $array_tmp);
->where($db->qn('field_id') .' IN (:field_ids)')
->bind(':field_ids', $field_ids, ParameterType::STRING)
I will be grateful for information on how to do it properly.

why not just do

 ->where('field_id IN ('.implode(',', $array_tmp).')');

Works in J3 so should work in J4

If the $array_tmp are strings they will need individually quoting, so you would need to use something like this:

->where('field_id IN (' . implode(',', array_map([$db, 'quote'], $array_tmp)) . ')')

It works fine in "standard" quering. But Joomla developers are uses now  Prepared Statemens.
They works fine except IN clause. After few tests it looks like $field_ids is quoted somewhere during data bind or query execution and returns only record for first ID (cropped after first comma).
I will put this on Issue tracker.
Thanks for help!

->whereIn($db->quoteName('field_id'), $array, ParameterType::STRING) is used for this sort of thing - leave out the last variable if the array is integers.

Note: whereIn rather than where

I sent this message to the list by email previously. Does that not work any more?

->whereIn('field', $array)

But best to look up the whereIn call.
