There is no explicit binary type in Firebird. It can be accomplished using the CHAR type with a special character set, which tells the database that it is binary data and there is no collation. (called OCTETS). Because of that, we also need the character set to decide the exact column type. And also refactor some parts of the driver: - Create class to determine internal type from firebird type, subtype, scale and character set. - Use internal type (DataType::XXX) in XDatabaseMetaData::getTypeInfo() indirectly. (We want to return a Firebird type for each internal type, not in the opposite direction.
