Select null as xyz from sysibm.sysdummy1

P: 11

Why is it that this command doesn't work in DB2.
I have to create a view in which one of the columns has to be
null(Don't ask me why that should always be null, because the view in
Oracle and DB2 should have same columns and Oracle view has col as
So i try ...
Create view......null as col.......

It fails in DB2, but works in Oracle.

Please tell what should be done to set the field as null.

Thanks a lot

Well You Can Select Null same as in Oracle (i.e select Null as Val1 from dual). Try the following SQL in DB2 (v 9.5)

Select cast(NULL as CHAR) as v1 From sysibm.sysdummy1

and to make sure that it is returning Null i check the results using nvl

Select nvl(cast(NULL as CHAR),'ok thi is null') as v1 From sysibm.sysdummy1

I tried these Command in Toad for DB2
