如何使用多列SQL获取小计？

Question

希望生成有关销售订单和销售报价的报告，该报告将汇总和汇总以给出每个报价和订单的小计。

对于组合在一起的“文档编号”（订单/报价），其总“行金额”。

也很高兴能获得总计，但不是100％必需。

我尝试使用ROLLUP来生成此文件，但没有成功。

要获得小计行，您需要多个查询或在客户端进行汇总。通过多次查询，您可以多次查询数据存储或将初始详细信息放入临时表中，然后获取摘要。下面是多次查询。在两次查询之间存在数据更改的轻微风险。

很高兴看到示例数据或表结构。根据您所拥有的，关于您要实现的目标的最佳猜测如下。

1. 尽管在这种情况下正确，但理想情况下属于where子句。将其移至where子句后，我们不再需要在分组中，也不再需要在group by中包含SH。[Document Type]。

2. 对您的群组进行了重新排序。只是为了比较select语句中的所有列以确认没有丢失

3. 添加了一些聚合列。每个订单，每个销售人员，每个客户和总计的总和。您可以使用任何这些示例来找出所需的确切总数。
