Hello All,
I need to find a workaround for my addition problem.
I have a list of values in 3 columns derived from a left join
where the last column is the sum of the 2 on the left.
i.e.
select cola, colb, sum(cola + colb) from ....
cola colb total
2 3 5
2 2 4
now my problem comes into play when one of the
columns is empty. I always get a NULL or empty total.
this makes sence since NULL + 5 does not produce anything.
cola colb total
3
1
4
etc.
Any work around for this, do I have to use a
Pg language? I guess I could write a script in perl
to take of this for me but I would like to tap
the brains here to see it can al be done in the
SQL.
Thanks
