Well, the difference is that in a data oriented language, you do not need to map Objects to relations. You can get the data back in the relational format and use it as is in your app. So you don't need an ORM. You might still have a library to help you build dynamic SQL queries, but no object-relational mapping needed.

You can do that in an OO language, too; relations (whether constant or variable, and whether there data is held locally by the program or remotely, as in an RDBMS) are perfectly valid objects.
