Real-Time NL2SQL Lookup for Historical Prices
Scenario: A user, interested in assessing the long-term investment potential, submits the natural language query: "What is the highest price in Falls Church in the year 2000?"
Process:
- Submit Query: The user enters their natural language question into the chatbot interface.
- Generate & Execute SQL: LangChain translates the plain English query into an optimized SQL statement, which is then executed directly on the Supabase PostGIS database.
- Post-process & Render: A lightweight ChatOpenAI chain refines the raw JSON result into concise, human-readable text, which is then displayed in the chat interface.
Result: The system successfully identified the highest price in Falls Church in the year 2000 as $308,002.64, demonstrating its ability to provide precise, historical data with ease.
RailEstate's chatbot also features robust handling for both valid and unsupported queries, providing structured answers for in-domain requests and informative fallbacks for out-of-scope cases.
