How in SQL could you "zip" together records in separate tables (à la the UNIX paste(1) utility)?

For example, assuming two tables, A and B, like so:

   A          B
========    ====
Harkness    unu
Costello    du
Sato        tri
Harper
Jones

How could you produce a single result set

   NAME  | NUM
===============
Harkness | unu
Costello | du
Sato     | tri
Harper   | NULL
Jones    | NULL

?
