Hybrid Querying Over Relational Databases and Large Language Models
Summary: Presents SWAN: the first cross-domain benchmark of 120 beyond-database questions over four real-world relational schemas for hybrid DB+LLM querying. Proposes schema-expansion and UDF-based integration, evaluates GPT‑4 Turbo (≤40% exec accuracy, 48.2% factuality) and exposes optimization needs and accuracy/factuality gaps.
