Oracle Analytic Functions - Getting the running sum for a column in a query

This is one of those things that I should have known - but didn't and had to figure out...

I needed to keep a running sum of a field in a query. I thought it had something to do with the "OVER ()" command but I finally found the answer:
"OVER (ORDER BY my_number ROWS UNBOUNDED PRECEDING)"

Below you'll find an example and Happy Holidays to all...Rich

SQL>CREATE TABLE test (
  2      my_number   NUMBER);

Table created.

SQL>INSERT INTO TEST VALUES (1);

1 row created.

SQL>INSERT INTO TEST VALUES (2);

1 row created.

SQL>INSERT INTO TEST VALUES (3);

1 row created.

SQL>INSERT INTO TEST VALUES (4);

1 row created.

SQL>COMMIT;

Commit complete.

SQL>SELECT  my_number,
  2         sum(my_number) OVER 
  3          (ORDER BY my_number ROWS UNBOUNDED PRECEDING)
  4          AS "RUNNING SUM"
  5  FROM    test
  6  ORDER BY my_number;

     MY_NUMBER    RUNNING SUM
-------------- --------------
             1              1
             2              3
             3              6
             4             10
