AutoCAD’s built-in DBCONNECT lets you link drawing objects to external database records, but it does not automatically update label text from SQL updates in real time. To achieve what you want, you’ll need to use dbConnect with database-linked attributes or fields, then run a data update inside AutoCAD using DATAUPDATE (or manually refresh the link) after making changes in SQL. For dynamic updates without manual refresh, you’d need custom automation using AutoLISP, .NET API, or VBA to query SQL and push the values into AutoCAD objects. Autodesk’s dbConnect documentation is a good starting point.
