DQL to get r_object_id From DRL

I have a situation like this. I checked out a file from documentum (File is a dita-map ). File has a reference to another file in the repository. DRL is dctm://MILLENNIUM/0500006480003b2e?DMS_OBJECT_SPEC=RELATION_ID. From this, I assume that 0500006480003b2e is the relation ID. If so how do I get its ObjectID .

I need the object ID of the child in order to checkout that do开发者_如何转开发cument separately.

Thanks in Advance.

Assuming your assumptions are correct and assuming my memory is correct

select child_id, child_label, permanent_link from dm_relation 
where r_object_id = ID('0500006480003b2e')

If permanent_link is TRUE then the child_id is the document's i_chronicle_id and the child_label is used to differentiate the versions.

If permanent_link is FALSE the the child_id is the document's r_object_id.
