We build and govern only the canonical core SQL query in Oracle 23ai, while all filter combinations, groupings, and ad-hoc views are generated dynamically at runtime or via AI inference in Oracle APEX 24.2."

      "q": "How do runtime and inference-based filters work for business users?",
      "a": "Each core SQL view powers an Oracle APEX 24.2 Interactive Report or Smart Filter page alongside Oracle 23ai Select AI natural-language inference. Users can toggle faceted filters, save private or public runtime report views, schedule email subscriptions, or type natural-language questions that synthesize safe WHERE predicates against the governed core view at runtime."
