When opening a SDE view directly in oracle with Oracle SQL Developer to see the Data we get the following error message:
ORA-01445: cannot select ROWID from, or sample, a join view without a key-preserved table
The SDE view shows correctly in ArcCatalog but now in SQL Developer we get this error message.
It looks like the error is caused by the field "SHAPE", because removing this field allows to Open the view and see the data.
WHERE FC.ProjectID IS NOT NULL
AND FC.ProjectID = TableView.ProjectID;
