Roman,

Thank you again for the response. This makes things simple, since our
Report Generator won't have to worry about handling schema qualifiers in
SQL queries when it runs against Firebird.

Regards,

Alex.

I think the possibility to connect to multiple databases described in
documentation belongs to GPRE, an SQL pre-processor for different
languages (but not Java). Also it does not provide you a possibility to
issue a query over multiple databases, it is only a way to open two
[independent] connections. If I'm not wrong, the only possibility to
issue a query over multiple databases is QLI, you can consider it as a
shell with its own language. However it is only available as standalone
tool which handles querying, merge-join, etc. internally. Firebird
server does not provide such possibility yet.
