SQL help me please with multi nested childs
Making some guesses about what you’re trying to do, you’ll have to alter the table schema to do this efficiently. The ‘ancestry’ gem (https://github.com/stefankroes/ancestry ) can do the migration and update your parent_id-based data to enable all its cool features.

Ancestry is a gem that allows the records of a Ruby on Rails ActiveRecord model to be organized as a tree structure (or hierarchy). It employs the materialized path pattern and exposes all the standard tree structure relations (ancestors, parent, root, children, siblings, descendants), allowing all of them to be fetched in a single SQL query. 3,136 stars by now

Another option is to use something like AwesomeNestedSet which does basically the same thing as the previous suggestion but with a whole lot more flexibility (and likely more reliably performant).
