Dears, I connected QGIS to Oracle DB which contains tables with GEOMETRY and spatial data.
When trying to add some tables to the layer window, I saw this error message: 2021-07-13T16:48:15 WARNING Primary key field 'INSERT_DATE' for view not unique. This INSERT_DATE is not my primary Key column. I have a column called ID which is the primary key. How can I tell QGIS which columns are the primary keys in the tables I want to add to layers? Please advise. Regards, Yamen
