Oracle11g 已设置分组的SQL不会返回相同的结果

我有2个分组集查询。在进行分组设置之前，我检查了结果是否完全相同。L_TIM_53_ID和L_TIM_54_ID的值始终为2458120。但是我通过以下两个查询得到了不同的结果

问题A：

SELECT NVL(TABLE_A.PRD_LVL_MEMBER_ID,2147483647) AS L_PRD_1_ID
,NVL(TABLE_A.TIM_52_ID,2147483647) AS L_TIM_52_ID
,NVL(TABLE_A.TIM_53_ID,2147483647) AS L_TIM_53_ID

问题B：

我们可以清楚地看到发布的组集是针对表A.TIM\u 54\u ID的，我不知道这两个SQL之间有什么区别。为什么他们返回不同的结果
