something like this? If your tuples are not single columns, then you'll have to use dynamic sql to achieve the same result.with
table_1 as
(select '|Xyz|Abc|Def|' tuple from dual
table_2 as
(select '|Data1|Data21|Data31|Data41|Data51|' tuple from dual union all
select '|Data2|Data22|Data32|Data42|Data52|' tuple from dual union all
select '|Data3|Data23|Data33|Data43|Data53|' tuple from dual union all
select '|Data4|Data24|Data34|Data44|Data54|' tuple from dual union all
select '|Data5|Data25|Data35|Data45|Data55|' tuple from dual
select case the_row when 1
                    then tuple
                    else '|---|---|' || substr(tuple,instr(tuple,'|',1,3) + 1)
       end tuple
  from (select substr(a.tuple,instr(a.tuple,'|',:one_one),instr(a.tuple,'|',:one_one + 1)) ||
               substr(a.tuple,instr(a.tuple,'|',1,:one_two) + 1,instr(a.tuple,'|',1,:one_two + 1) - instr(a.tuple,'|',1,:one_two)) ||
               substr(b.tuple,instr(b.tuple,'|',1,:two_one) + 1,instr(b.tuple,'|',1,:two_one + 1) - instr(b.tuple,'|',1,:two_one)) ||
               substr(b.tuple,instr(b.tuple,'|',1,:two_two) + 1,instr(b.tuple,'|',1,:two_two + 1) - instr(b.tuple,'|',1,:two_two)) tuple,
               rownum the_row
          from table_1 a,table_2 b
order by the_rowRegards
