ArcGIS Pro 2.6.8; Oracle 18c 10.7.1 EGDB:
I've created a database view using SQL Developer. The view is not registered with the geodatabase.
I can see that the view isn't registered by right-clicking on the item in the Catalog Pane. The fact that the Register with Geodatabase option is not greyed out tells me that it's not yet registered.
That works as expected.
However, I think I should be able to determine if the item is registered with the GDB by viewing the Catalog item properties. That information is not explicitly stated.
Could the Catalog item properties be enhanced so that it explicitly indicates if an item is registered with the geodatabase? For example, below the Data Type row, add a row like this: "Registered with the Geodatabase: Yes/No". I imagine non-registered tables should be considered too, not just non-registered views.
For EGDB views: I suspect this only applies to the Catalog item properties window, not the Contents feature layer properties, since feature layers based on views are actually query layers that SELECT * from the view. So the Contents feature layer isn't pointing directly to the view.
However, it might be different for mobile geodatabase views and file geodatabase views, since those geodatabases don't support query layers; the Contents feature layer references the view directly. So perhaps the Contents feature layer properties should indicate if the mobile or file geodatabase item is registered with the geodatabase too (in addition to the Catalog item properties), since the Contents feature layer properties references the view directly.
