A Fix for the Fixation on Fixpoints accepted at CIDR 2023

Tübingen returns to CIDR, this time for the 2023 edition to be held in Amsterdam (NL), January 8–11, 2023. We will report on our recent explorations into alternative forms of iteration in SQL—generalizing recursive common table expressions—that are easier to write and read as well as more efficient to evaluate than WITH RECURSIVE (which has been established more than 20 years ago but since then has been largely left untouched).
