Transform Dashboard Queries with GPT-5 & Postgres Workflow

Transform Dashboard Queries with GPT-5 & Postgres Workflow

Elevate your data analysis effortlessly with our cutting-edge "Transform Dashboard Queries with GPT-5 & Postgres Workflow". By converting plain-language questions into powerful SQL queries, this n8n automation workflow allows you to seamlessly interact with your Supabase/Postgres database.

What this workflow does

This workflow ingeniously leverages OpenAI's GPT-5 to bridge the gap between natural language and SQL, removing technical barriers:

• Start by sending a POST request with a `chatInput` question to the workflow's webhook endpoint.
• Utilizes an in-memory schema cache; if necessary, it reloads from the `schema_cache` table to ensure an updated schema version.
• Filters schema down to only the relevant tables and columns, using previous questions for context, to craft a precise prompt for OpenAI.
• Generates a PostgreSQL query based on the chatbot's memory of prior queries and the provided schema.
• Executes and reviews the SQL query using OpenAI, ensuring accuracy and efficiency.
• Aggregates and formats the query results into a user-friendly format, such as a Markdown table, with specialized formatting for data types like currency or dates.
• Crafts a concise, conversational response with OpenAI, returning the answer alongside a chart and the SQL command within a JSON response.

Use cases

• Dynamic Reporting: Auto-generate complex reports without writing a single line of SQL by asking intuitive questions.
• Real-time Insights: Instantly access and assess the latest data from your Supabase/Postgres database, enabling quicker decision-making.
• Non-technical Access: Make your data accessible to a wider team by allowing non-technical members to ask questions and get accurate results.

Technical details

• Tech Stack/N8n Nodes: Leverage the power of n8n with nodes such as if, code, webhook, postgres, aggregate, and n8nn8n-nodes-langchainagent.
• Integration Requirements: Securely add your Postgres credentials for database access, and ensure OpenAI API credentials for model interaction (e.g. gpt-5-chat-latest).
