lob_mode

Can be one of:

• FBSQL_LOB_DIRECT - LOB data is retrieved directly. When data is fetched from the database with fbsql_fetch_row(), and other fetch functions, all CLOB and BLOB columns will be returned as ordinary columns. This is the default value on a new FrontBase result.
• FBSQL_LOB_HANDLE - LOB data is retrieved as handles to the data. When data is fetched from the database with fbsql_fetch_row(), and other fetch functions, LOB data will be returned as a handle to the data if the data is stored indirect or the data if it is stored direct. If a handle is returned it will be a 27 byte string formatted as @'000000000000000000000000'.
