QIBASE for Borland InterBase
The Qt InterBase plugin makes it possible to access the InterBase and Firebird databases. InterBase can either be used as a client/server or without a server in which case it operates on local files. The database file must exist before a connection can be established. Firebird must be used with a server configuration.
Note that InterBase requires you to specify the full path to the database file, no matter whether it is stored locally or on another server.
QSqlDatabase db;
db.setHostName("MyServer");
db.setDatabaseName("C:\\test.gdb");
