It's easier to do this in SQL and not in Perl.

You need to do an outer join between the two tables.

select t1.name, t2.name
from t1
left outer join t2
on t1.name = t2.name

You'll get back a two column result set. If a name is in both tables then it will appear in both columns. If it only appears in t1 then the second column will contain NULL.

You then need to write the Perl that handles that and creates your list.
