RE: what to put in place of null

Harv,

Well, it depends on the type of dd and dd1, doesn't it?

how about: (for the case where these are VARCHAR2)

cursor c1 is
select dd,dd1,dd2,dd3 from dd
union
select 'ddstub','dd1stub',dd2,dd3 from dd1;

and likewise for other datatypes, mutatis mutandis.

Yours in Data,

etc.
