Question
How can one make a dummy table in DB2?
Dear Experts
I'm actually new in DB2, and I'd like to know how one can make a dummy table to replace the a table when one a character in the that table is missing
Let me explain:
I have a table called A and I'm making a dummy called table B
Table A's & B's structure:
Described in the Picture below
Because the A Table has the scenario where the entire row can be empty and that's where the problem is. The column name A_TYPE in the Table A should never be empty.
And I only have the "select" privilege (rights), so I decided to create a dummy table in DB2 and make a union join
select
a.A_DATE,
du.A_TYPE
from
A_TABLE a,
, (
SELECT 'B' as A_TYPE FROM sysibm.sysdummy1
union
SELECT 'S' as A_TYPE FROM sysibm.sysdummy1
union
SELECT 'U' as A_TYPE FROM sysibm.sysdummy1
union
SELECT 'W' as A_TYPE FROM sysibm.sysdummy1
union
SELECT 'T' as A_TYPE FROM sysibm.sysdummy1
) du
WHERE
a.A_DATE = '01.01.2009'
group by
a.A_DATE, du.A_TYPE
union
select
A_DATE,
A_TYPE,
from
A_TABLE
WHERE
A_DATE = '01.01.2009'
group by
A_DATE, A_TYPE
But this result doesn't seem quiet right. Can any one help me out?
