Sure enough!
... so the answer to the NVL question is that coalesce does it, and the
answer to Jeff Eckermann's question goes something like this:
test=> select * from hiho;
one |two
----+------
hiho|
hip |hop
|hophip
(3 rows)
test=> select one,two,coalesce(one,'')||coalesce(two,'') from hiho;
one |two |?column?
----+------+--------
hiho| |hiho
hip |hop |hiphop
|hophip|hophip
(3 rows)
Thanks Stephan!
