I like this format as I find it easier to read.
But I think the line 'when n2 > n1 then n2' is superfluous.

I have

> select min(case
>    when n2 > 0 then n2
>    else n1 end) as refVal from TABLE

Err yeah...

So now I need to do something like (I think)

with t as (
 select uniqueKeyflds, min(case
    when n2 > 0 then n2
    else n1 end) as refVal from TABLE
)

Then join my table to T
