VCoT‑SQL is a framework that improves text‑to‑SQL generation by training two complementary models on curated reasoning traces. It uses clause‑level chain‑of‑thought templates verified through execution and schema alignment, and a validator that detects syntactic, semantic, and type errors. The approach achieves high execution accuracy on BIRD and Spider datasets, outperforming larger closed‑source models while relying only on 7B open‑source models.
arXiv:2606. 15598v1 Announce Type: new Abstract: Text-to-SQL aims to translate natural language questions into executable SQL queries over structured databases, enabling non-expert users to access data intuitively.
LIMIT (Less Is More for Instruction Tuning in Text-to-SQL) challenges the belief that large instruction corpora are necessary for effective Text-to-SQL models. The framework uses a four‑stage data‑centric process—difficulty‑aware filtering, chain‑of‑thought synthesis, LLM‑as‑judge quality scoring, and genetic algorithm optimization—to select a compact set of examples that still achieve full schema coverage. On the BIRD and Spider benchmarks, LIMIT’s 796 and 863 samples enable Qwen3‑8B to reach 69.1% and 88.9% execution accuracy, outperforming methods trained on twenty times more data and setting a new state‑of‑the‑art for open‑source approaches.
