title: Unimplemented feature error in stored procedure
body: <p>I sm getting error:</p>
  
  <pre><code>ORA-03001: unimplemented feature
  ORA-06512: at "SYS.CHANGE_SSAN", line 127
  ORA-06512: at line 2
  Process exited.
  </code></pre>
  
  <p>on this line :</p>
  
  <pre><code>  alter_constraints_disable(hosm_list.hosm);
  </code></pre>
  
  <p>This is the procedure:</p>
  
  <pre><code>PROCEDURE alter_constraints_disable (hosm_cd   IN VARCHAR2)
  
  IS
      BEGIN
  
      for constraint_list IN (select table_name, constraint_name 
                                     from dba_constraints 
                                     where owner=hosm_cd 
                                     and constraint_name in ('List of constraints removed for space.'))
      LOOP
          execute immediate 'alter table '||hosm_cd||'.'||constraint_list.table_name||' DISABLE constraint '||constraint_list.constraint_name;
      END LOOP;
  END;
  </code></pre>
  
  <p>The issue appears to be coming from the next line instead of the call to alter_constraints_disable.</p>
  
  <p>execute immediate 'select person_id bulk collect into dup_ssan from '||hosm_list.hosm||'.dod_per order by 1 asc';</p>
  
  <p>Is there something I am missing about bulk collect</p>
