I have my doubts as to whether DB2 V8 for zOS supports the WITH clause.
Try this:
select
distinct
value_list.C1 ,
case when Table_val.C2 is null then '?' else Table_val.C2 end
from
Table_val
right outer join
( values
('V2'),
('V2'),
('V3'),
('V4'),
('Vempty'),
('Vempty')
) AS value_list
...
I'm wondering about the VALUES clause as well.
For a LEFT OUTER JOIN the rewrite would be an IN list.
Not obvious (to me) how to get rid of it for a ROJ other than inserting
the content into a temp table.
Cheers
Serge

Hello Serge
I've checked that DB2 OS/390 8.1.5 accepts WITH clause but doesn't accept
VALUES clause in the context I need.
This is the final SQL sentence we will use:
select
distinct
value_list.C1 ,
case when Table_val.C2 is null then '?' else Table_val.C2 end
from
Table_val
right outer join
(
select 'V2' as C1 from sysibm.sysdummy1 union
select 'V2' as C1 from sysibm.sysdummy1 union
select 'V3' as C1 from sysibm.sysdummy1 union
select 'V4' as C1 from sysibm.sysdummy1 union
select 'Vempty' as C1 from sysibm.sysdummy1 union
select 'Vempty' as C1 from sysibm.sysdummy1 union
) as Value_list
on
Table_val.C1 = Value_list.C1
where
Table_val.C1 <'Vempty';
Thank you very much
