Oracle 11g R2 Schema Setup:

CREATE TABLE numbers ( value ) AS
SELECT               0 FROM DUAL UNION ALL
SELECT          123456 FROM DUAL UNION ALL
SELECT        12345678 FROM DUAL UNION ALL
SELECT   1234567890123 FROM DUAL UNION ALL
SELECT 123456789012345 FROM DUAL UNION ALL
SELECT 900000000000000 FROM DUAL UNION ALL
SELECT 700000001200000 FROM DUAL UNION ALL
SELECT 543000000000000 FROM DUAL;
