The problem it targets is familiar: enterprise warehouses contain thousands of tables with abbreviated column names, informal metric definitions, and hidden join conventions that raw table names do not expose. The benchmark results are specific: on CRUSH4SQL, the approach hit 96.4% table recall at 20 candidates; on SEDE, incorporating query history alone pushed table recall at 5 from 52.1% to 92.3%; on BIRD, schema-first context cut SQL execution errors from 15.6% to 6.2%. Against a BM25 baseline, semantic retrieval gained 32.8 points on table recall at 5.\n\nThe text-to-SQL space has no shortage of papers chasing accuracy on clean academic datasets; the harder problem is getting the right schema into context when dealing with a sprawling, permission-gated warehouse. Retrieval-augmented generation research has focused largely on document corpora — this work applies the same logic to structured metadata, which is a meaningful shift in framing.\n\nEnterprise warehouses are messier than any benchmark captures — whether workload memory and lineage expansion survive three mergers and four naming conventions is a question only production deployments will answer.","[\"text-to-sql\",\"database\",\"retrieval\",\"ai\"]","2026-06-30T04:00:00.000Z","2026-06-30T08:13:10.679Z","2026-06-30T08:13:13.508Z","published",null,[],"ai",[26,27,28,24],"text-to-sql","database","retrieval",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.28387",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
