Reward-SQL: Boosting Text-to-SQL via Stepwise Execution-Aware Reasoning and Process-Supervised Rewards
Researchers have developed Reward-SQL, a novel framework designed to enhance the performance of large language models (LLMs) in Text-to-SQL tasks. This approach addresses limitations in current RL-based methods by incorporating stepwise execution-aware reasoning and process-level rewards. Reward-SQL utilizes a divide-and-conquer strategy with intermediate view validation and structured Common Table Expressions (CTEs) to improve accuracy and interpretability. The framework includes a process reward model (PRM) that provides fine-grained, execution-aware supervision, which is then integrated into both RL training and inference stages to stabilize optimization and improve trajectory exploration.
