CodePudding user response:

You are using is BDE components, the company's machine is installed when installing a DELPHI ODBC service (on the control panel can see), and is not installed on your machine, so you can't access the database. If using ADO component, you may not have set up the database connection component relative path, use absolute paths, of course also cannot access the database.
