MTIR-SQL: Multi-turn Tool-Integrated Reasoning Reinforcement Learning for Text-to-SQL
As large language models (LLMs) are increasingly used in Text-to-SQL tasks, Reinforcement Learning (RL) has become a common method for improving performance. Existing methods primarily rely on static execution feedback, which restricts real-time error correction. However, integrating multi-turn tool invocation along with dynamic feedback could significantly improve adaptability and robustness, ultimately enhancing model performance. To address these issues, we propose MTIR-SQL, an innovative Multi-turn Tool-Integrated Reasoning reinforcement learning framework for Text-to-SQL.

Reinforcement Learning in MTIR-SQL
MTIR-SQL leverages advanced Reinforcement Learning (RL) techniques, specifically an extended GRPO algorithm, to optimize its policy. Unlike traditional methods that treat execution feedback merely as scalar rewards, MTIR-SQL integrates multi-turn tool invocation and dynamic feedback directly into the learning process. This enables the model to adapt its reasoning dynamically and correct errors in real-time, moving beyond static LLMs. The framework enhances GRPO with trajectory filtering and removes KL loss constraints to ensure stable training and prevent distributional collapse, which are common issues in complex multi-turn interaction scenarios.
Multi-Turn Tool-Integrated Reasoning
At the core of MTIR-SQL is a novel multi-turn tool-integrated reasoning paradigm. This approach allows the LLM to interact seamlessly with external tools, such as SQL executors, at each reasoning step. By integrating database execution feedback, the model can generate context-sensitive queries and progressively refine its outputs. This iterative process, where tool invocation and dynamic feedback are interleaved, significantly improves the adaptability and robustness of the model. The framework is built on RL-Factory with standardized MCP-compatible tool invocation, ensuring high extensibility and interoperability across various database operations.
Text-to-SQL Applications
MTIR-SQL is specifically designed for the Text-to-SQL task, aiming to automatically translate natural language questions into executable SQL queries. By enabling non-technical users to access structured data in natural language, it finds wide applications in business intelligence, data analytics, and interactive question answering. The framework addresses key challenges in Text-to-SQL by overcoming the limitations of static execution feedback and the instability of multi-turn tool interactions. Experimental results on benchmarks like BIRD and SPIDER demonstrate its superior performance, achieving high accuracy in complex SQL generation scenarios.

Final Answer
Case Study: Impact of Reward Components
Problem: Current RL methods treat execution feedback merely as scalar rewards, wasting rich tool information and leaving static LLMs unable to adapt their reasoning dynamically.
Solution: MTIR-SQL introduces a streamlined reward mechanism focusing on Format, Execution, and Result correctness, guiding the model with real-time feedback.
Key Results:
- Execution Reward (Re): Removing Re results in the largest performance drop (3.9% decrease), highlighting its crucial role in NL-to-SQL conversion.
- Result Reward (Rr): Excluding Rr leads to a significant decline (4.3% drop), underlining its importance in ensuring functional correctness.
- Format Reward (Rf): A balanced Rf is beneficial, guiding the model to maintain a specific structured response format.
