我有一个相当复杂的多重嵌套查询集，需要将其聚合到一个视图中，但是我一直在获取度量标准不存在错误。每个组件运行正常，但是当我将它们全部放在一起时，会出现错误并指出无效的操作：函数sum（数字，数字，数字）不存在
任何帮助将不胜感激

错误消息告诉您，没有功能sum(numeric, numeric, numeric)。 sum()对集合中组中所有行的表达式求和。如果要在一行中添加值，只需使用+。
例如更改
sum(LM_DSP.Delivered_Shipments, LM_DA.Delivered_Shipments, LM_f.Delivered_Shipments) as Delivered_Shipments
收件人：
LM_DSP.Delivered_Shipments + LM_DA.Delivered_Shipments + LM_f.Delivered_Shipments as Delivered_Shipments
...以及所有其他类似的东西。
