SafeQL: Search-based Refinement for Safe and Efficient LLM-based Text-to-SQL

Summary: SafeQL makes the DBMS an active search guide for LLM Text-to-SQL refinement. It incrementally repairs erroneous query components in a DBMS-validated safe-query space, improving execution accuracy and efficiency over full-query regeneration. (summarized by gpt-5.6-luna on Aug 17 2026)
