About This Workflow
Overview
This n8n workflow empowers users to interact with their PostgreSQL databases using conversational AI. The core logic revolves around an AI Agent that acts as an intermediary between the user and the database. When a chat message is received, the AI Agent node processes the request, identifying the intent and potentially formulating SQL queries. It utilizes various tools, including Execute SQL Query, Get DB Schema and Tables List, and Get Table Definition, to effectively query the database. The OpenAI Chat Model node provides the natural language processing capabilities, and Chat History ensures context is maintained across conversations. This workflow is ideal for users who need to extract information from their databases without writing complex SQL.
Key Features
- Natural language database querying via chat interface.
- AI Agent for intelligent request interpretation and SQL generation.
- Integration with PostgreSQL for data retrieval.
- Support for multiple AI tools like schema listing and table definition fetching.
- Chat history for maintaining conversational context.
How To Use
- Set up your PostgreSQL and OpenAI credentials in n8n.
- Trigger the workflow by sending a chat message.
- Ask questions about your database in natural language (e.g., "Show me all users from the 'users' table.").
- The AI Agent will process your request, generate and execute SQL queries, and return the results.
