Could you use UNION?

Ok, say you have two tables

TABLE1:
pol_num       build_value
1                     10
3                      15
5                       11

TABLE2:
pol_num       auto_value
2                     7
4                      1
5                       21


How would you get a result set that would include all polnum in both
tables,
but with both values if the policies match?  The closest I can get is using
a left join.

SELECT T1.polnum, T1.build_value, T2.auto_value
 FROM T1
 LEFT JOIN T2
 ON T1.polnum = T2.polnum

but that won't give me pol_num 2 and 4 in table2.

Any ideas?
