Sql server 2008 按计数排序不正确-SQL（MS Access 2007）

概述： 比较不同账户代理农产品的日常交易，找出代理和公司持有量之间的差异，仅显示新情况；当前交易中的代码，但不是以前交易中的代码

目标： 按最高频率的代码（即苹果）对交易进行排序

当前表格：

如何修复使用正确的频率顺序（苹果、芒果、葡萄）？

我认为问题在于您的分组过于精细

在这种情况下，从

GROUP BY

子句中排除三个金额列（

AgentHolding

、

CompanyHolding

和

Difference

），并在输出中聚合它们（

sum

）

以下是这一变化将产生的效果的示例：

注意：我省略了

left join

和

PrevTrade

表，因为我不知道它的结构和数据，但希望这能说明我的意图。

Awesome..谢谢！这是更清洁和工作。由于查询会动态比较2个表/2个日期，所以我添加了左连接。
