XiYan-SQL: A Multi-Generator Ensemble Framework for Text-to-SQL

Introduction in Short

XiYan-SQL is an innovative framework for LLM based Text-to-SQL.

It contains:

  1. M-schema a semi-structured schema representation method.

  2. Training Stragegy a LLM training strategy with tuned generation model for SQLite (to release soon).

  3. Ensemble Strategy a multi-generator ensemble strategy with selection model (to release soon).

  4. DateResolver a date understanding and reasoning enhanced model, major for Chinese.

  5. MoMQ a multi-dialects Text-to-SQL MoE model based on Qwen (to release soon).

  6. Database Description Generation a method and corresponding code for automatic description generation for Text-to-SQL (to release soon).

Full Intro.

To tackle the challenges of large language model performance in natural language to SQL tasks, we introduce XiYan-SQL, an innovative framework that employs a multi-generator ensemble strategy to improve candidate generation. We introduce M-Schema, a semi-structured schema representation method designed to enhance the understanding of database structures. To enhance the quality and diversity of generated candidate SQL queries, XiYan-SQL integrates the significant potential of in-context learning (ICL) with the precise control of supervised fine-tuning. On one hand, we propose a series of training strategies to fine-tune models to generate high-quality candidates with diverse preferences. On the other hand, we implement the ICL approach with an example selection method based on named entity recognition to prevent overemphasis on entities. The refiner optimizes each candidate by correcting logical or syntactical errors. To address the challenge of identifying the best candidate, we fine-tune a selection model to distinguish nuances of candidate SQL queries. The experimental results on multiple dialect datasets demonstrate the robustness of XiYan-SQL in addressing challenges across different scenarios. Overall, our proposed XiYan-SQL achieves the state-of-the-art execution accuracy of 75.63% on Bird test, 89.65% on the Spider test set, 69.86% on SQL-Eval, 41.20% on NL2GQL. The proposed framework not only enhances the quality and diversity of SQL queries but also outperforms previous methods.
