Subject Re : Are domains supported ?
Date Thu, 16 Nov 2006 09:35:24 GMT
Hi,

Thanks for pointing me to the opened issue (as said before I am not familiar with this site
... yet).

I understand that domains are really difficult to be fully supported as there is no real standard
ont his (on some rDBMS they're called user datatypes).

But I would think a first easy step, would be to "translate" the domain into its equivalent
into the XML file.
This way an export - import can be done : the imported database would not have any domains
(or user datatypes or whatever it's called) but at least it will be possible to create it
and to do some work when a domain has been defined.

Right now, I can not use DDL-Utils for my database ... and that's a shame !

 
Have fun,
L@u

There is an open issue for this
(http://issues.apache.org/jira/browse/DDLUTILS-84) but it is not
currently targeted for a release. Domains are problematic in that they
are not supported by all databases, and providing an alternative
implementation so that you can use them in your XML regardless of
whether the db has native support, is tricky.

cheers,
Tom
