          table_comments,
       (SELECT ccm.comments column_comments
          FROM dba_col_comments ccm
         WHERE     ccm.owner = TC.OWNER
               AND ccm.table_name = tc.table_name
               AND ccm.column_name = tc.column_name)
          column_comments

       AND o.object_type = 'TABLE'
       AND NOT EXISTS
                  (SELECT 1
                     FROM dba_mviews mv
                    WHERE mv.owner = o.owner
                          AND mv.container_name = o.object_name)
       AND t.owner = o.owner
       AND t.table_name = o.object_name
       AND tb.tablespace_name = t.tablespace_name

       AND tc.table_name = t.table_name
       AND tc.data_length > 15
       AND tc.data_type NOT LIKE ('TIMESTAMP%')
       AND (tc.data_precision IS NULL OR tc.data_precision > 15);(The line containing the string of astrixes, that is the table that the error says does not exist)
can someone help me where I am going wrong.
Thanks

what if I create the view in SYS for few minutes until i can complete the task i was assigned and after that drop the view I created in SYS schema, would that have any effect on the database?Uh, yeah .. SYS isn't any better an option than SYSTEM.
Those schemas are "off limits" to us ... ignore them .. pretend they do not exist. (seriously ..)
Sounds like you need a new schema to store your application objects.
