[firebird-support] Querying between databases

[craig_...@coxcolvin.com [firebird-support]]

I have many separate database files that have all the same structure, but hold 
data from different customers. In each database, I have a series of tables that 
are used to supply valid values through foreign keys.  These tables and the 
data they hold are exactly the same in each database.  When I need to update a 
valid value in one, I have to make that same change in all the other databases. 
 Is there a way to keep the valid value tables in a separate database and build 
queries that access these tables from a second database?  The goal is the have 
a single set of valid value tables, instead of multiple copies.
