Sql 分组集未聚合结果

我最近才开始使用这个函数，所以请原谅这个问题，如果它是愚蠢的

我有一个现有的查询，我意识到使用这个查询可以帮助创建额外的分组，类似于小计

在本例中，我希望在如下层次结构中进行聚合：

年>月>利润中心>日期

此查询返回的结果示例

如您所见，我的分组集返回零。 我的问题是，为什么

我的问题如下

我的问题是，为什么（分组设置为零）

因为您使用的聚合函数（如

SUM（）

或

COUNT（）

）的方式不能汇总为小计。您使用的是一组“相关子查询”，它们确实使用了

COUNT（）

，但在计算这些子查询时，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）：

---

注意：您需要注意“隐式转换”，如果pcd.price\u center\u id是一个整数，那么不要使用“194”，但是如果它是一个varchar或类似的值，那么就不要使用整数。我还建议您尽量保持where子句的“顺序”，以便更容易阅读。

您能发布示例数据和预期输出吗？请以a或文本形式发布样本数据。
