Geometry type of view in Oracle Spatial

Hi Jakob,

AFAIK, in addition to inserting entries into user_sdo_geom_metadata, you must also define a primary key for your views so they would appear in the list of features to be registered. Have you done anything similar to the following?

alter view AFL_BROEND add primary key (YOUR_PK_COLUMN) disable;

Jeff,

I was communication unclear:

- afl_broend is a view of gis_drain_wells (create view afl_broend as select * from gis_drain_wells).

- Yes, as the view is basicly just a renaming of the table - no where clause or joins. Other than the definition above and the index' layer_gtype there is no garantee.

- Yes, layer_gtype is set to MULTIPOINT for the spatial index of gis_drain_wells - id actually expect it to be just "point". Not sure why its multipoint and not point.

- I use Bentley Map SS2 (standalone) v08.11.07.434

- "Register Feature Wizard" only shows me tables - no views - I'd expect it to give me all entries from mdsys.user_sdo_geom_metadata!? Views are registered in user_sdo_geom_metadata.

Regards. Jakob

Jakob,

A few questions.

Do both views refer to the same base table?
Is each view defined in such a way as to guarantee that all rows returned contain the same geometry type?
For the AFL_BROEND feature class, what is the layer_gtype parameter defined for the index of the referenced table?
What version and edition of Bentley Map are you using?
Do you see similar behavior when you use the "Register Feature" process in the Bentley Geospatial Administrator application to create a graphical source?
