PremiseSQL: Evaluating Premise Critique and Abstention in Text-to-SQL Systems

PremiseSQL introduces a benchmark of 1,800 flawed natural language to SQL (NL2SQL) queries, grouped into four categories of premise failures, alongside their original valid counterparts. The study evaluates large language models’ ability to critique flawed premises and abstain from generating misleading SQL, using an evaluation framework across three prompting settings. Results show that current models tend to trust premises and rarely critique them, while stronger critique-oriented prompting improves detection but also raises false invalid judgments and reduces SQL generation for valid queries.

From Passive Response to Proactive Correction: Enhancing LLM Robustness Against Input Fact Perturbations

The paper introduces DEDUCE, a three‑stage framework that turns large language models into proactive error correctors by detecting input fact errors, devising correction strategies, and delivering reliable answers. It also presents MisFactQA, a dataset of factual errors, and new metrics for robustness evaluation. Experiments on TruthfulQA, FalseQA, and MisFactQA show significant gains in accuracy and error correction across Qwen, LLaMA, and Gemma models.

ACTS-SQL: Agentic and Critic-Oriented Tree-Structured SQL Correctness with Large Language Models

arXiv:2608. 15145v1 Announce Type: new Abstract: Large Language Models (LLMs) have been increasingly adopted in Text-to-SQL systems, yet SQL errors remain a major obstacle in real-world Text-to-SQL inference pipelines.

Never the Number: Structural Abstention for AI Systems Whose Answers Are Consumed as Fact

arXiv:2608. 13926v1 Announce Type: new Abstract: Large language models have made natural language interfaces to databases (NLIDB) newly credible, but LLM text-to-SQL systems fail in a way that matters for deployment: a hallucinated column or a mis-aggregated total yields a fluent wrong answer, indistinguishable at the point of use from a right one.
