Goal

We need to migrate a small Delphi service that performs database operations without service interruption.

Constraints & Uncertainty

The service is built with RAD Studio 11 or newer and runs as a Windows service with a local SQL Server database. Documented runtime update mechanisms are Live Code, limited to console-style apps, and Hot Reload, which requires special debug mode and is described for Windows desktop apps. It is unclear if either feature can update database-access code in a running service.

Specific Questions

Can Live Code update database-access code in a running Delphi service without restart?
Does Hot Reload support non-UI modules in a Windows service for runtime logic updates?
