dbExpress 8.0.1 and oracle 11 client

Post by ZehWeh » Thu 25 Nov 2021 11:00

Hello everyone!

We got a problem with the devart dbExpress driver for oracle.

We use Embarcadero C++ Builder and upgraded to 11.0 Alexandria. For that, we installed the newest version (8.0.1) of devart dbExpress driver. With that version comes the dbexpoda41.dll in version

If we use this dll combined with the installed oracle client 11, the communication doesn't work right. If we insert or update data in our database tables there will be inserted a lot of "¿" instead of the right text in the fields.

To test it, we exchanged the dbexpoda41.dll (version with the old dbexpoda41.dll ( and everything works fine.

Is there a bug in version 8.0.1?

To be sure, we searched and installed all update to your development environment. So our C++ Builder is updated.

Thanks for help.

Best regards

Devart Team
