Help with SQL!

Hello. I know it's a simplest thing but I'm stuck.
There are 5 variables from a same table: A, B, C, D and E, as below
A
-------
0.5

B
-------
1.2

etc


I want to bring each one of them back in separate rows, but as one variable (call it Level 2 for example) so the result of query will look like

Level 2 Rate
-------- --------
A 0.5
B 1.2
C 0.4
D 3.1
E 1.0

I'm working in Oracle 9.1, using SQLPlus. Any help will be welcome! Please!!

Thanks in advance
Fiona

Code:

---

select 'A' "Level 2", A "Rate" from my_table
  UNION ALL
select 'B' "Level 2", B "Rate" from my_table
  UNION ALL
etc

That worked brilliantly - thank you!

Another method:

Code:

---

09:57:52 SQL> desc my_table
 Name                  Null?    Type
 --------------------- -------- ----------------------------
 C1                            NUMBER(38)
 C2                            NUMBER(38)
 C3                            NUMBER(38)
 C4                            NUMBER(38)

09:58:24 SQL> select * from my_table ;

        C1        C2        C3        C4
---------- ---------- ---------- ----------
        1          2          3          4


select  decode(code,1,c1,2,c2,3,c3,4,c4)
from my_table, (select 1 code from dual union all
                select 2 code from dual union all
                select 3 code from dual union all
                select 4 code from dual  )
/
DECODE(CODE,1,C1,2,C2,3,C3,4,C4)
--------------------------------
                              1
                              2
                              3
                              4

09:59:32 SQL> spool off
