Can SQL queries across namespaces be made?

Question

Is it possible to make a query across tables in different namespaces?

Eg:

select A.TS as A_TS, B.TS as B_TS 
from ns1.schema.table as A left join ns2.schema.table as B on A.id = B.id

At least, is it possible to get tables A and B using the same ODBC connection? As far as I can see, the namespace is established when making the connection.

The only way to do it is by using namespace as it is supposed to be, you can add package and global mapping, to new or existing namespace/s. So, desired tables will be available from one namespace together.
