If the databases are all on the same MySQL server, then you could simply 
ensure that the user you are connecting to the server as has appropriate 
permissions for all the databases and the amend your queries to prefix 
the table name with <databasename>. - MySQL allows queries to cross 
databases on the same host.


SELECT id, username, attribute, value, op FROM db1.radcheck WHERE 
username = '%{SQL-User-Name}' ORDER BY id

you could even make the database name a dynamic expansion

SELECT id, username, attribute, value, op FROM 
%{control:Local-Database}.radcheck WHERE username = '%{SQL-User-Name}' 

where Local-Database is an attribute you define in your local dictionary 
and populate in your policy before calling the SQL module.
