Storing data in cursors?

Question

Hi,
I am new to PL/SQL. Need to store the following data somewhere (without creating DB tables or text files) and perform cartesian join.
data_set_1 = 100 rows ( contains numbers 1 to 100)
data_set_2 = 2 rows ( contains numbers 1 and 0)
data_set_3 = 4 rows (contains chars R,M,S,N)
data_set_4 = 3 rows (contains chars M,F,U)
data_set_5 = 9 rows (contains numbers 1 to 9)
The problem is creating this data on the fly. Can 5 cursors be declared to hold the above data and can a cartesian join (below) be performed on them?
select * from cursor1,cursor2,cursor3,cursor4,cursor5
Thanks!

You can use WITH clause.
with data_set_1 as
(select rownum from (select * from dual
connect by level<=100))
data_set_2 as
(select 1 d2 from dual
union all
select 2 from dual),
data_set_3 as
(select 'R' code from dual
union all
select 'M' from dual
union all
select 'S' from dual
union all
select 'N' from dual)
select * from data_set_1, data_set_2, data_set_3
ROWNUM                 D2                     CODE
1                      1                      R   
1                      1                      M   
1                      1                      S   
1                      1                      N   
1                      2                      R
