Addressing the Problem of the Missing dbxConnections.ini File

There is an issue with RAD Studio 10.4.x related with dbExpress configuration, that you can work around by creating a new configuration file.

When you install RAD Studio 10.4 (or 10.4.1) or Delphi or C++Builder, there is an error in the installation script that causes a configuration file to be missing. The lack of this file, that the IDE expects, causes a few errors reported for example as:

RSP-29199: Error on ConnectionName selection in TSQLConnection

RSP-30831: Error in dbxconnections

In practice, if you use the dbExpress section of the Database Explorer to create a new connection, you end up with an access violation in the IDE:

dbxini_01-7719813

dbxini_02-2280087

Instead, if you try to select a connecting in the SQLConnection component, you’ll see the proper error message:

dbxini_03-3606157

The issue is caused by the fact in the the installer leaves separate, partial configuration files (dbxconnections.win.x files) in the C:\Users\Public\Documents\Embarcadero\Studio\dbExpress\21.0 folder rather than merging them in a single dbxconnections.ini file. The ideal solution is to merge them manually in a new dbxconnections.ini file, but you can also just create a new empty dbxconnections.ini file or use one from a previous version of RAD Studio.

As soon as you add that file (and restart RAD Studio), the IDE will behave correctly and your new connections will be added to the ini file.

dbxini_04-6425204

Notice also that the dbExpress library (or DBX) is formally deprecated and not maintained any more, which is why we missed this configuration issue. The recommendation is to migrate from it to FireDAC (see this RAD Studio docWiki page) or some other database access library.
