Register geodatabase table - how to choose the right entity types

[YvesThibault]

Hi,

I'm not and expert with the geodatabase concept.

I need to register geodatabase tables.  So, I will use the "sdetable -o register" and "sdelayer -o register" commands.

In my geodatabase, I have different entity types like simple line(l), point (p), annotation (A) and polygon (????).

When I look at the help of the register command (http://help.arcgis.com/en/geodatabase/10.0/admin_cmds/support_files/datamgmt/sdelayer.htm), I'm not sure with entity type I have to select for the polygon.  As I understand, we can have a combinaison of more than one entity type (like -e nac+).

Does anybody know which entiy type I must use for polygon ?  Do you know how to determine the right entity type?

Thank's in advance!

Yves

Hi Yves,

In a polygon for example you might use "nac+" which stands for:

n: nil (null geometry allowed)

a: area (REQUIRED)

c: cad (Allows for storing curves)

+: multipart features

You will always need to specify it as and area type, but the others are optional.

What storage type are you using? ST_GEOMETY, SDO_GEOMETRY?

Hi Christian,

We use ST_GEOMETRY ...

Thanks Yves, with that response, I don't have anything to add to my statements above. I would mention that equivalent to creating a polygon in ArcCatalog would be "nac+"

Thank you very much Christian!

For the record,

• Point feature classes are "npc"
• Multipoint feature classes are "npc+",
• Polyline feature classes are "nlsc+", and
• Polygon feature classes are "nac+"

3-D (well, 2.5-D -- X/Y with Z) would add "3" and measured shapes add "M" (any order).

Geodatabase annotation isn't a separate topology class in enterprise geodatabases; I wouldn't recommend using the deprecated command-line tools to interact with them.

The documentation can be found in many places, including here​.
