Is there a way to get the AVG of all specified NON-NULL columns in one row?
Right now I am doing this in a little script, but it would be nice if I
could do something like this:
DATA
---------
id1 0 4 4 NULL 3 NULL
I want the average of 0,4,4,3 ie (0+4+4+3)/4
is there a way to do this in a SELECT query?
Thanks!
Graeme
