Vlado Cingel recounts his story where he needed common table expressions within SQL for a project he was working on and wrote a patch to AREL and ActiveRecord which he submitted to the Rails Core. Since it hasn't been accepted, he's supporting it as a gem.
Vlado explains what Common Table Expressions (CTEs) are, how they work, and where they're used.
