I have built an ODBC connection on an Oracle database. The table can be added. However no attributes (columns) are shown in the table. How can I add those?

 

 

The attributes (columns) can be added retroactively. For this click on the table (TABELLE1) and on Edit . The Edit Data Source dialog opens. In the dialog it is obvious that the table is indeed prompted however the columns are not retrieved.

 

Click on the button Retrieve Columns. Thereby the columns are added and are now available for further steps.
