Hello All,

I am wondering if this is possible and how.

I have a table with fields A, B, C, D and E. Any of these can contain nulls.
What I need to do is to be able to perform a select that removes nulls.

EG:

if A = 'A'
B = NULL
C = NULL
D = 'D'
E = 'E'

what I would like returned is

A, D, E, NULL, NULL.

Can anyone suggest a way to do this? I will need to select from this and
hopefully add som simple conditions.

Would a VIEW be the way to go or will I have to use a stored procedure?

Regards,

Stephen.
