SELECT UPPER(TO_CHAR(TO_DATE(500,'J'),'Jsp')) || '/=' AS new_value
FROM dual;  

线索是Date拼写格式.

添加对negative numbers的支持:

WITH cte AS
(
  SELECT 10 AS num      FROM dual
  UNION ALL SELECT -500 FROM dual
  UNION ALL SELECT 0    FROM dual
)
SELECT num AS old_value,
       decode( sign( num ), -1, 'NEGATIVE ', 0, 'ZERO', NULL ) ||
       decode( sign( abs(num) ), +1, to_char( to_date( abs(num),'J'),'JSP') ) || '/=' AS new_value
FROM cte

添加了对float的有限支持:

EDIT 2:

Adding limited support for float:

WITH cte AS
(
  SELECT 10 AS num       FROM dual
  UNION ALL SELECT -500  FROM dual
  UNION ALL SELECT 0     FROM dual
  UNION ALL SELECT 10.3  FROM dual
  UNION ALL SELECT -10.7 FROM dual
)
SELECT 
  num AS old_value,
  decode( sign( num ), -1, 'NEGATIVE ', 0, 'ZERO', NULL )
  || decode( sign( abs(num) ), +1, to_char( to_date( abs(TRUNC(num)),'J'),'JSP') )
  ||
  CASE
     WHEN INSTR (num, '.') > 0
     THEN  ' POINT ' || TO_CHAR (TO_DATE (TO_NUMBER (SUBSTR(num, INSTR (num, '.') + 1)),'J'),'JSP')
     ELSE NULL
  END AS new_value
FROM cte
