ORM library

Hi there,
I'm working on a project where I need to consolidate (?) queries from two different databases :
DB1
- table1
- - id
- - name
- - address
DB2
- table1
- - id
- - comment

And I need to display the data this way :
id | name | address | comment
1 | john | NY | some things
2 | phill | LA | other things

And, (but I don't think it matters) I only need/want to write in DB2

Is there something in Doctrine or DMZ that allow me to do that out of the box, or will I need to make it myself ? (in this cas I will use DMZ, as the other parts of my project are pretty simple)

Thanks a lot.
