db2 CASE statement in ORDER BY clause

1 New Member
Hi all !

This is my first post here. I am totally new to db2 and last night I faced with this problem:

I want to order my query results by different columns in ORDER BY clause using CASE statement as follows:

DECLARE cursor1 CURSOR WITH RETURN FOR
.....
....
.....
ORDER BY( CASE WHEN ORDER_MODE = '1' THEN 2 ELSE 5 END )

Of course this does not work (I don't know why ). When I write:

ORDER BY( CASE WHEN ORDER_MODE = '1' THEN 5 ELSE 5 END )

This also does not work.

When I write:

ORDER BY ( 5 )

It's working fine, but there is no CASE so it;s not my intention.

Does anybody knows what can be wrong with my statement ?
Thanks for help in advance.

I've always been mistified why you can't use a column alias in the group by clause (i.e. you have to re-iterate the entire expression in the group by clause after having already done it once in the select statement). I'm mostly a SQL hobbiest, so it's possible that I am not doing this in the most efficient manner. Anyone care to comment on this with relation to the following example (is there a way to acheive this without re-stating the...
