Approximate String Joins in a Database (Almost) for Free

Summary: Proposes approximate string joins on commercial DBs via q-grams; encodes match positions and counts, rewriting the predicate as a relational expression. Shows gains vs UDFs for full-string and substring joins; validated on real data and a prototype. (summarized by gpt-5-nano on Feb 09 2026)
