New TRUST-SQL framework enables Text-to-SQL over unknown schemas

By PulseAugur Editorial · [1 sources] ·

Researchers have developed TRUST-SQL, a novel framework for Text-to-SQL parsing that operates effectively even with unknown database schemas. This system uses a structured four-phase protocol and a Dual-Track GRPO strategy to identify and verify relevant metadata, improving credit assignment for exploration rewards. Experiments show TRUST-SQL achieves significant improvements over standard methods, outperforming schema prefilling baselines without prior metadata knowledge. AI

IMPACT This research could significantly improve how AI agents interact with and query complex, unknown databases in real-world enterprise environments.

    TRUST-SQL: Tool-Integrated Multi-Turn Reinforcement Learning for Text-to-SQL over Unknown Schemas

    arXiv:2603.16448v3 Announce Type: replace Abstract: Text-to-SQL parsing has achieved remarkable progress under the Full Schema Assumption. However, this premise fails in real-world enterprise environments where databases contain hundreds of tables with massive noisy metadata. Rat…
