Towards Automating Domain-Specific Data Generation for Text-to-SQL: A Comprehensive Approach
This research addresses the critical need for high-quality, domain-specific Text-to-SQL datasets to enhance the reliability and robustness of natural language interfaces for databases. The authors propose SELECTCRAFT, a novel automated generation approach that leverages existing databases to create realistic Text-to-SQL datasets. As a proof of concept, they generated BANQIES, a substantial financial Text-to-SQL dataset of over 1 million samples. They also introduce BANQL, a large language model (LLM) fine-tuned on BANQIES, which demonstrates significant improvements in accuracy and generalizability compared to state-of-the-art models. The work highlights the importance of domain-specific data for Text-to-SQL tasks and offers a flexible, scalable solution for enterprise AI applications.

The research introduces SELECTCRAFT, an automatic generation approach for creating realistic Text-to-SQL datasets. This involves an initialization step using general-purpose LLMs to define database schemas and column values, followed by SQL query generation based on real-world statistical distributions from datasets like Stack-SQL. Finally, an SQL-to-Text model transforms these queries into natural language questions, incorporating a paraphrasing step to enhance diversity.

BANQL Performance Boost
90 BLEU Score (BANQL-1B on Test Set)BANQL-1B (fine-tuned on BANQIES) achieves a BLEU score of 90% on test_1, significantly outperforming general-purpose LLMs and other Text-to-SQL models.
The main challenges addressed include the scarcity of high-quality, domain-specific Text-to-SQL datasets and the limitations of generic models. SELECTCRAFT provides a scalable solution for data generation, and BANQL demonstrates how fine-tuning on such data leads to robust, domain-aware LLMs.
Addressing Domain Specificity in Finance
In the financial sector, accurate and reliable Text-to-SQL translation is paramount due to the sensitive nature of data. Generic models often fail to capture industry-specific terminology and query patterns. BANQIES and BANQL provide a tailored solution, ensuring high accuracy for financial queries. For example, queries involving 'transaction_amount' and 'account_type' are handled with significantly higher precision, leading to more reliable financial reporting and analysis. This approach mitigates risks associated with data inconsistencies and system failures in critical enterprise applications.
Key Point: BANQL outperforms general-purpose models by up to 37.6% in BLEU score on financial domain-specific tests.
Energy Efficiency of Fine-tuning
65 Times Less Energy (BANQL-1B vs CodeLlama-34B)Fine-tuning smaller models like BANQL-1B on domain-specific datasets is significantly more energy-efficient for large-scale inference than using massive general-purpose LLMs, reducing operational costs and environmental impact.

Your Enterprise AI Implementation Roadmap
A phased approach to integrating domain-specific Text-to-SQL AI into your operations for maximum impact and minimal disruption.
Phase 1: Data Strategy & Schema Integration
Define specific data domains and integrate existing database schemas with SELECTCRAFT for initial data generation. This involves leveraging LLMs to formulate theoretical schemas and validating potential column values and relationships.
Phase 2: Dataset Generation & Refinement
Utilize SELECTCRAFT to generate a large-scale, domain-specific Text-to-SQL dataset (e.g., BANQIES). Employ SQL parsing for syntactic and semantic validation, and incorporate paraphrasing techniques to enrich NLQ diversity. This phase emphasizes producing high-quality, realistic query-question pairs.
Phase 3: Model Fine-Tuning & Customization
Fine-tune a code-based LLM (e.g., StarCoder2) on the generated dataset to create a domain-specific Text-to-SQL model (e.g., BANQL). This step leverages adapter modules (LoRA) for efficient training, ensuring the model is specialized to the enterprise's unique data and query patterns.
Phase 4: Validation & Deployment
Rigorously test the fine-tuned model against distinct, expert-crafted test sets to ensure accuracy, generalizability, and robustness. Integrate the validated BANQL model into enterprise applications, enabling seamless natural language interaction with databases for improved data retrieval and analysis.
