Description

EDIT: as of Feb 2 2025, limbo supports derived tables from FROM clause subqueries, but not other kinds.

Contributor guide

Research direction
Examine the current subquery implementation for FROM clauses, then identify which subquery forms are missing (e.g., scalar subqueries, EXISTS, IN). Study SQLite's subquery handling and plan changes to the parser and executor.
