Alter Domain

Alter Domain

(OP)
Does anyone know if it is possible to alter a domain without droping then re creating?

If not possible then how can I find if any dependancies in triggers, views etc exist for that domain. Can't see anything in Information_Schema tables.

Confused :(

RE: Alter Domain

There is not (yet anyway??) any ALTER DOMAIN. When you drop a domain the default value and any restrictions are moved to the columns using the DOMAIN. Triggers and views have to be recreated...

To fix the columns using the domain you have to: ALTER TABLE tab1 ALTER col1 newdomaintype after (re-)creating the new domain.

Dependencies should be in the view INFORMATION_SCHEMA.EXT_OBJECT_OBJECT_USED

RE: Alter Domain

Hi,

I cannot find anything in the docs about an ALTER DOMAIN statement

As for dependencies, you might want to check INFORMATION_SCHEMA.COLUMN_DOMAIN_USAGE
