Chat2DB gom SQL client và AI assistant vào cùng một workspace, hỗ trợ hơn 30 database như MySQL, PostgreSQL, Oracle, ClickHouse, MongoDB và Redis. Điểm đáng thử: text-to-SQL, query history, chỉnh dữ liệu, biểu đồ, ER diagram và chạy local-first. Nhưng SQL do AI tạo vẫn phải review trước khi execute. Dùng AI như copilot, đừng dùng như autopilot. #repo #claude #codex #cursor #zendeveloper
