GRIPS: An Empirical Study of Pre-SQL Grounding Information for SQL Generation

Read the original on arXiv Computation and Language →

The paper introduces GRIPS, a three‑stage method that extracts structured pre‑SQL grounding information—such as table, column, value, and relation links—to guide text‑to‑SQL generation. Experiments on TempTabQA‑C and BIRD show that GRIPS‑Adaptive outperforms baseline SQL Static in 18 of 20 settings, boosting average accuracy by 11.8 percentage points and cutting model‑call token usage by 47.8%. The study demonstrates that explicit grounding improves accuracy and efficiency, while adding more pre‑SQL data does not always help.

EvoSQL: Memory-Augmented Critic-Generator Co-Evolution for Text-to-SQL

arXiv:2607. 20489v1 Announce Type: new Abstract: Text-to-SQL has advanced rapidly with large language models, but complex database queries still require reasoning beyond one-shot generation, including multi-step decomposition, execution-based diagnosis, and targeted correction.

Querying an astronomical database using large language models: the ALeRCE text-to-SQL system

arXiv:2606. 18108v1 Announce Type: cross Abstract: We develop a text-to-SQL (structured query language) system based on large language models (LLMs) using in-context learning and apply it to the Automatic Learning for the Rapid Classification of Events (ALeRCE) astronomical database.
