I'm transferring many tables (967) from single BDE .DBF files (old driver DbIV) to Firebird 2.5.
I utilize Delphi 7 as environment and ZEOS components to Firebird connections: the work is enough easy. A large number of old queries contain UNIONS and JOINS of tables (-> single files .DBF), but now the old .DBF tables are transferred in different Firebird Databases. For example, with the two tables Municipalities.Dbf and ZipCodes.Dbf, I can write with BDE a query "SELECT * FROM MUNICIPALITIES.DBF a INNER JOIN ZIPCODES.DBF b ON ()... WHERE..."; now the first table is in WorkCom.fdb database, and the second table is in the TabCom.fbd database: how to join to day the tho tables? My program utilizes this queries and I would want to find solutions that give a fast result as BDE. I know that is not possible for Firebird to join tables that "resides" in different databases (.fdb), but I must find a solution as elegant as possible to join the same FB tables previously joined with .DBF files. Do you have any suggestion as to how to solve this problem?
