This worked for me. I got the getlong code from a post by ORACLEtune on expertsexchange.

select object_name
from dba_objects
where object_id in (select obj#

                    from sys.view$  
                    where getlong('sys.view$','text',rowid) like

'%<table_name>%')

---

create or replace function  getlong( p_tname in varchar2,
                                     p_cname in varchar2,
                                     p_rowid in rowid ) return varchar2
  as
      l_cursor    integer default dbms_sql.open_cursor;
      l_n         number;
      l_long_val  varchar2(4000);
      l_long_len  number;
      l_buflen    number := 4000;
      l_curpos    number := 0;
  begin
     dbms_sql.parse( l_cursor,
                     'select ' || p_cname || ' from ' || p_tname ||
                                                        ' where rowid = :x',
                      dbms_sql.native );
      dbms_sql.bind_variable( l_cursor, ':x', p_rowid );
  
      dbms_sql.define_column_long(l_cursor, 1);
      l_n := dbms_sql.execute(l_cursor);
  
      if (dbms_sql.fetch_rows(l_cursor)>0)
      then
         dbms_sql.column_value_long(l_cursor, 1, l_buflen, l_curpos ,
                                    l_long_val, l_long_len );
     end if;
     dbms_sql.close_cursor(l_cursor);
     return l_long_val;

end getlong;

I need to devise a method of comparing the TEXT column of dba_views against varchar2. End result I want to find the views that reference a particular table within its text.

example (which ~obviously~ will not work): select view_name
from dba_views
where text like '%<table_name>%

I understand that a query or PL/SQL procedure of this sort would be long running, but getting the concept to work would be a start.

TIA
