Usage of BOOLEAN and GUID types in Firebird and Interbase now available with IBProvider
GUID type is currently not supported by any Firebird and Interbase server, but it is frequently used by different clients (for example, in ADO Entity Framework).
Boolean type is supported by Interbase starting from 7th version and is not supported by Firebird server. IBProvider can work with this type, but it lacks support from other servers.
New release of IBProvider 126.96.36.19946 supports Guid and Boolean types at driver level, and now you can freely use these types in your applications irrespective of Interbase and Firebird server versions.
