Off topic, but why aren't you just doing this:
select column_name,column_id
from user_tab_columns
where table_name = 'ITEM_GROUPS'
  and column_id in (25,26,31,32,24)If you want a guaranteed order, then you will have to specify and ORDER BY.
For instance this one (though I don't expect that this is what you are looking for).
order by
  case column_id
   when 25 then 1
   when 26 then 2
   when 31 then 3
   when 32 then 4
   when 24 then 5
  endYou might try this (not tested):
select c.column_name,c.column_id
from user_tab_columns c
     ,(select to_number(column_value) as col_id
             ,rownum as rn
       from The(Select cast(str2tbl('25,26,31,32,24') as mytabletype) from dual) x
where c.table_name = 'ITEM_GROUPS'
  and c.column_id = x.col_id
order by x.rnEdited by: Toon Koppelaars on Apr 27, 2011 12:53 PM
