Testing Containment of Conjunctive Queries Under Functional and Inclusion Dependencies (Extended Abstract)
Summary: Establishes CQ containment (hence equivalence/non-minimality) in NP for inclusion dependencies when either no FDs or FDs are key-based, under infinite-database semantics. Finite databases may add containments, but a compactness theorem rules out finite-only counterexamples in the key-based case. (summarized by gpt-5-mini on Feb 09 2026)
