         columnid number ;
          columnval number ;
          columntitle varchar(4000);

          BEGIN
          -- open c2 ;
           for rec in c2 loop
           select title into columntitle from hr.columns where id = rec.id
           insert into hr.rowaction(columnid,newvalue,oldvalue,actiondate)
             select  id ,:new.columntitle,:old.columntitle,sysdate
             from hr.tabletiltes
             where id = rec.id
          select title into columntitle from hr.columns where id = rec.id;
          dbms_output.put_line(columntitle);
