Reward-SQL: Boosting Text-to-SQL via Stepwise Execution-Aware Reasoning and Process-Supervised Rewards
Summary: Reward-SQL introduces CoCTE, progressively composing SQL with execution-validated intermediate views and structured CTEs. Its entropy-weighted, execution-aware process reward model supervises both RL training and inference, improving accuracy, interpretability, and cross-domain generalization.
