n8n SQL Agent is Gone? Build Your Own (Step-by-Step Guide)
Stop writing complex SQL queries by hand. In this video, I'll show you how to build your own simple, powerful AI agent in n8n that can answer natural language questions about your database. We're building this from scratch because the default SQL agent in n8n doesn't exist anymore. I'll walk you through every step: setting up a free Postgres database using Supabase , connecting it to n8n , and building the complete AI agent workflow. The best part? We'll thoroughly test it —from basic filters and aggregations to complex multi-table joins and temporal analysis —to prove it actually works and can provide real data-driven insights. ━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔗 RESOURCES & LINKS 💬 Download the full resource in Skool: https://www.skool.com/erictech 📅 Work With Me New Projects - Free Strategy Call: https://calendar.app.google/sB9KrJP6e...
