 When a rowid column is made unused the table becomes unsupported by Streams as per the following output

SQL> select * from dba_streams_unsupported;

------------------------------ ------------------------------ --------------------------------------- ---
<OWNER>  <TABLE_NAME> unsupported column exists NO


For the columns which are not supported by Streams gets entered into the view DBA_STREAMS_UNSUPPORTED.
But when that unsupported column we make as UNUSED column then it should not be shown into DBA_STREAMS_UNSUPPORTED view, as UNUSED columns are being supported by streams.
