To divide the table based on number of rows

Question

Hello,
I am trying to divide a table based on the number of rows and then to process it.
Say i have a table TEST_XXX which contains 50 rows, what i would like to do is,
to access rows in multiple of 10. How can we do this ?
What i was thinking is, once the table gets created and row are filled in,
add a new column to the table and run a procedure which inserts 1 to first 10 rows
and 2 to next 10 rows and 3 to next 10 row ...etc. Based on this we can process
the first set of rows then next set or rows etc ....
is there a better way to do this ?
Code to create the table :
CREATE TABLE TEST_XXX
  A_ID   VARCHAR2(10),
  B_ID   NUMBER,
  c_ID   VARCHAR2(10),
  D_ID   NUMBER
)Code to add rows:
DECLARE
BEGIN
  FOR I IN 1..50
  LOOP
      INSERT INTO TEST_XXX VALUES('ABCDE',123,'ZYXWV',321);
  END LOOP;
  COMMIT;
END;The original problem is, i do have a huge table, and i write a sql query to process it,
when i process it selecting all values from table, it is very slow.
But when i process it in small chuks(say 100 rows) it works fine.
Thats how i was the above approach in mind.
