ID_Number|Subject_Code|Grade
000001   |Math        |Dropped
000001   |English     |Passed
000001   |Physics     |Passed
000002   |Math        |Passed
000002   |English     |Passed
000002   |Physics     |Passed
000003   |Math        |Passed
000003   |English     |Passed
000003   |Physics     |Passed

现在我想要SELECT DISTINCT ID_Number其中所有的subject_code都应该有等级作为通过，查询应该返回000002和000003，因为000001有1个放弃的主题，其他不包括的等级是'撤回'和'失败'。
