分组集不是聚合结果
我最近才开始使用这个功能，所以请原谅这个问题，如果它是无法解释的。
我有一个现有的查询，我已经意识到可以通过使用此查询来创建额外的分组，类似于小计。
在这个例子中，我想要在这样的层次结构中进行聚合：
年份＆gt;月份>利润中心＆gt;日期
此查询带回的结果示例
正如您所看到的，我的分组集返回零。 我的问题是，为什么？

我的问题是，为什么（分组设置为零）？
因为您没有使用EventSplit= data.Event.str.split('~',expand=True).stack()
Day_split = data.Day.str.split('~',expand=True).stack()
new_data = data.join(pd.Series(index=Day_split .index.droplevel(1), data=Day_split .values, name='Day_split '))
new_data = data.join(pd.Series(index=EventSplit.index.droplevel(1), data=EventSplit.values, name='EventSplit'))
或SUM()等聚合函数，而不是可以归纳为小计。您正在使用一组＆＃34;相关子查询＆＃34;它使用COUNT()但是在评估它们时，外部查询只将这些列视为数据（而不是聚合）。
示例（当然未经测试）：
COUNT()注意：你需要注意＆＃34;隐式转换＆＃34;，如果pcd.profit_center_id是一个整数，那么不要使用＆＃39; 194＆＃39;，但如果它是varchar或类似的话不要使用整数。我还建议你试着在某些＆＃34; order＆＃34;中保留where where子句。所以它更容易阅读。
