It suits users looking to automate SQL query generation with AI, manage large datasets efficiently, and produce interactive reports without deep technical knowledge.\n\n**Preparation**  \n- Create your Snowflake credentials in n8n with required host and account details, warehouse (e.g., \"computer_warehouse\"), database, schema, username, and password.  \n- Replace placeholder variables in schema retrieval workflows with your actual database and data source names.  \n- Verify the credentials by testing the connection; reset passwords if needed.\n\n"
