How to sort columns values in sql db2-400?

I have 10 columns with similar information, and I would like to sort them asc when greater than 0.
For instance, from this:

A1	A2	A3	A4	A5	A6	A7	A8	A9	A0
00	01	00	09	08	05	00	02	06	03

To this:

A1	A2	A3	A4	A5	A6	A7	A8	A9	A0
01	02	03	05	06	08	09	00	00	00

I been trying through min and max functions to no avail.

Answer

You can unpivot the data and reaggregate: One way is:

select max(case when seqnum = 1 then a end) as a1,
       max(case when seqnum = 2 then a end) as a2,
       . . .
from (select a.a,
             row_number() over (order by a desc) as seqnum
      from (select a1 as a from t union all
            select a2 from t union all
            select a3 from t union all
            . . .
           ) a
     ) a;
