Researchers have developed a new method for SQL schema retrieval, focusing on identifying relevant tables and columns for natural language queries. They adapted existing text-to-SQL datasets into retrieval tasks and found that standard embedders performed poorly. To address this, they proposed a corpus-adaptive fine-tuning technique that synthesizes queries from the target schema and mines hard negatives. This approach significantly improved recall and nDCG scores, establishing schema linking as a distinct retrieval task and offering a practical solution for enterprise-scale deployment. AI
