SQL & PL/SQL :: Columns Into Rows Conversion

I have the following query

select a.EV_ACTOR_NAME, round((b.total_transfer/(24 * a.Max_Throughput)) * 100) AVG_ThroughPut,round(((b.total_transfer/a.Max_Throughput) * 100 )) MAX_Throughput from
(select distinct EV_ACTOR_NAME,((max(EV_TRANSFER_RATE) over ( partition by EV_ACTOR_NAME)) * 60 * 60) /1024 Max_Throughput from dprt_events where EV_ACTOR_NAME is not null ) a,
(select distinct EV_ACTOR_NAME, (sum(EV_TRANSFER_SIZE) over( partition by EV_ACTOR_NAME)/1024/1024/1024) total_transfer from dprt_events where EV_ED_ID in (40,105,112) and EV_END_TIME between (sysdate - 20) -12/24 and sysdate - 20) b
where a.EV_ACTOR_NAME = b.EV_ACTOR_NAME

This is the output i get :

EV_ACTOR_NAME AVG_THROUGHPUT MAX_THROUGHPUT
------------ ------------- --------------
actor2 1 33
actor3 0 0
actor1 2 53

How do I convert the above out put to following format.

EV_ACTOR_NAME value1 value2
-------------- -------------- --------------
actor2 AVG 1
actor2 MAX 33
actor3 AVG 0
actor3 MAX 0
actor1 AVG 2
actor1 MAX 55

I tried the following

WITH data AS
(select level a from dual connect by level <= 3)
select EE_ACTOR_NAME,decode(a, 1, AVG_ThroughPut, 2, MAX_Throughput) value from
(

[Code]...

but i always get the following error ORA-00904: "A": invalid identifier
