About This Workflow
Overview
This workflow helps you understand your PostgreSQL database structure by retrieving table names, column names, data types, and nullability. It can then use this schema information to assist in generating more accurate SQL queries from natural language inputs.
Key Features
- Fetches all table names from a public PostgreSQL schema.
- Retrieves detailed column information (name, type, array status, nullability) for a specified table.
- Converts schema data into a JSON format for easier processing.
- Saves the schema locally for potential reuse.
- Can be triggered manually or via a chat interface.
- Extracts potential SQL SELECT statements from text.
How To Use
- Run Manually: Click "Test workflow" to execute the schema extraction part.
- Trigger via Chat: If a chat trigger is configured, interact with it to provide natural language queries.
- Configure Credentials: Ensure your PostgreSQL credentials are set up correctly for the "List all tables in a database" and "List all columns in a table" nodes.
- Observe Output: The workflow will output schema information and potentially extracted SQL queries.
