Question

下面的SQL查询有效...但是，当我添加“ FreightCostsPerOrderSplit”字段（3个新字段）时，出现以下所示的ORA-01747错误消息。这些约定类似于之前在SQL代码中所做的约定，我不确定是什么导致了此错误消息。

第49行错误 ORA-01747：无效的user.table.column，table.column，或列规范

在我发布此问题时，我想出了解决方案。我决定将此答案发布给可能遇到相同问题的其他人。

解决方案涉及在计算字段的除数中将COUNT(OHH.*)替换为COUNT(OHH.FieldName)。有关count(*) vs count(column-name)语法的评论，请参见答案部分。

, (SUM(cteLoadFreightAgg.TOTALFREIGHT)/ COUNT(OHH.*)) AS "TotalFreight_SplitPerOrder"

Answer 1

最初我的计算字段为：

, (SUM(cteLoadFreightAgg.TOTALFREIGHT)/ COUNT(OHH.*)) AS "TotalFreight_SplitPerOrder"。

对于所有3个计算字段，我将除数字段更改为引用特定字段，并且错误消息已解决。然后，一旦语法成功解析，SSRS报告就会给出“ #VALUE”错误消息，而我不得不使用CAST（）函数来获得正确的评估，而不是SSRS报告中的错误消息。

, CAST((cteLoadFreightAgg.TOTALFREIGHT/ COUNT(OHH.ORDER_SEQ_CODE) OVER(PARTITION BY OHH.LOAD_SEQ_CODE)) AS NUMERIC(9,2)) AS "TotalFreight_SplitPerOrder"

因此，在解决了原始错误消息之后，我然后发现我应该执行WINDOWING函数以按照报告要求所指定的值对值进行划分。

我在线阅读一些答案，以回答“为什么COUNT（*）给出错误消息时，COUNT（FieldName）求值？”。我遇到了一些博客文章，但它们主要是关于性能问题，而不是行计数划分或我收到的此错误消息。
