Referential integrity / Coded Value Domains

BenediktGrabenmeier — Tue, 08 Dec 2015 08:55:28 GMT

Hello!
Currently I have two problems to solve and I hope you can show me ways so solve them 😉

We are using an oracle database to store our map data and have established direct connections to edit the map in different versions.

Problem 1: We are using some additional (none versioned) tables to store key-value pairs. In ArcMap we would like to see the "values" instead of the keys. Google told me to use Coded Value Domains - but as I understood its not possible to integrate own database tables. Are there any ways to create those coded values domains "on the fly"?

Problem 2: We would like to use referential integrity with those Key-Value tables. Because of the versioning of the data it makes no sense to create foreign keys. Are there any solutions for this problem, too?

Regards

Benedikt

To create the code value domain from table you can use arcobjects (http://help.arcgis.com/en/sdk/10.0/ArcObjects_NET/conceptualhelp/index.html#//0001000003mt000000) or Table To Domain http://resources.arcgis.com/EN/HELP/MAIN/10.1/index.html#//001700000025000000 I understand what you mean but Geodatabase is an object relational ( http://desktop.arcgis.com/en/desktop/latest/manage-data/geodatabases/the-architecture-of-a-geodatabase.htm ) link useful: http://desktop.arcgis.com/en/desktop/latest/manage-data/gdbs-in-oracle/geodatabase-admin-vocabulary.htm

If you don't know ArcObjects you can also execute this task using out-of-the-box tools in Desktop/Pro and can easily automate this with python. You can see examples of the available tools below along with examples of they can be used.

Create Domain

Table to Domain

Add Coded Value To Domain

Assign Domain To Field

This is probably highly unrecommended:

I use this SQL query to view my domain values outside an Arc environment. (MSSQL)

SELECT

codedValue.value('Code[1]','nvarchar(max)') AS "Code",

codedValue.value('Name[1]', 'nvarchar(max)') AS "Value"

FROM sde.GDB_ITEMS AS items INNER JOIN sde.GDB_ITEMTYPES AS itemtypes

ON items.Type = itemtypes.UUID

CROSS APPLY items.Definition.nodes

('/GPCodedValueDomain2/CodedValues/CodedValue') AS CodedValues(codedValue)

WHERE itemtypes.Name = 'Coded Value Domain'

You can also limit it to just one of your domains like I have to view my domain "DOM_STATUS" code value pairs:

SELECT

codedValue.value('Code[1]','nvarchar(max)') AS "Code",

codedValue.value('Name[1]', 'nvarchar(max)') AS "Value"

FROM sde.GDB_ITEMS AS items INNER JOIN sde.GDB_ITEMTYPES AS itemtypes

ON items.Type = itemtypes.UUID

CROSS APPLY items.Definition.nodes

('/GPCodedValueDomain2/CodedValues/CodedValue') AS CodedValues(codedValue)

WHERE itemtypes.Name = 'Coded Value Domain'

AND items.Name = 'DOM_Status'

Have never tried, but maybe you could try writing to these tables too -- I stick to using the Arc tools so far!
