Compare Two Temporary Tables

Hi,

This is my problem:

There is one table. I extracted some information on that one table and placed it in two temporary table.

Temporary Table 1
------------------------------------
ID Data 1 Data 2
1 xxxx yyyyy
2 zzzz aaaaa
3 bbbb ccccc
4 dddd eeeee

Temporary Table 2
------------------------------------
ID Data 1 Data 2
9 xxxx fffff
10 zzzz aaaaa
11 bbbb ccccc
12 dddd ggggg

Now, I want to get the only the unique values from both tables into a single table.

Temporary Table 3
------------------------------------
ID Data 1 Data 2

1 xxxx yyyyy
4 dddd eeeee
9 xxxx ffff
12 dddd ggggg

How do I do it?

Thanks!
