You might want to look at this solution for doing cross-database JOINs:
EasySoft ODBC Join-Engine:
http://www.easysoft.com/products/data_access/odbc_odbc_join_engine/index.html
and then use our mxODBC to access EasySoft's Engine:
http://www.egenix.com/products/python/mxODBC/
or mxODBC Connect, if you have a client-server setup:
http://www.egenix.com/products/python/mxODBCConnect/
Some database engines also allow integrating external ODBC
data sources - the external tables then look like normal
database tables and can be used in JOINs as well. I know that DB2
and Oracle support this kind of setup. You can access those using
mxODBC as well.
