This workflow empowers users to interact with a database conversationally through an AI-powered agent. It dynamically generates SQL queries based on user requests, streamlining data retrieval and analysis.nnThis workflow integrates OpenAI with a Supabase database, enabling users to interact with their data via an AI agent. The agent can:n- Retrieve records from the database.n- Extract and analyze JSON data stored in tables.n- Provide summaries, aggregations, or specific data points based on user queries.nn"
