ExternalDatabases

The ExternalDatabases collection contains ExternalDatabase objects that represent external databases based on ODBC data sources linked with GDB. Access to collection items is possible by names of external databases. External databases cataloged in GDB can be accessible by their internal numbers. An internal number is generated when an external database is cataloged in GDB by the ExternalDatabase::Register method. Continuity of external database numbers is not guaranteed. Persistence of internal number of cataloged external database is guaranteed until performing GDB reorganization by the GDBEngine::CompactGDB method with the mode == gdbCompactNoKeepISN.
