SQL RPG question

I am joining 2 files as following:



SELECT cust, rollupcust

FROM arfile left join rollup on cust = rollkey

where cust between 29600 and 29699



The results would be

0001000 0001000

0001001 0001000

0001002 0001000

0001003 0

0001004 0001002





My question is, is it possible to have the sql statement return the value
from column 1 (0001003) in column 2 when the value is zero.

So the results would look like this:

0001000 0001000

0001001 0001000

0001002 0001000

0001003 0001003 - would return value of column 1 if result of
column 2 is zero

0001004 0001002





Hope this makes sense.
