Oracle
memorizza solo le frazioni fino al secondo in un DATE
campo.
Usa TIMESTAMP
invece:
SELECT TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9')
FROM dual
, possibilmente trasmettendolo a un DATE
quindi:
SELECT CAST(TO_TIMESTAMP('2004-09-30 23:53:48,140000000', 'YYYY-MM-DD HH24:MI:SS,FF9') AS DATE)
FROM dual
