这是我的代码，我已经转换了我的日期以获取月份名称。我需要帮助

Answer 1

仔细看。那个巨大的派生表（一个很好的有意义的名称btw）与最外面的查询具有相同的group by子句。这意味着[a]每个ItemCode和datename（month，ad.applicationdate）只有一行。因此，在外部查询中没有任何内容可以求和，因为它是按相同的列进行分组。

您还有以下表达式：

DateOfInspection =''

根据列名称高度可疑。 DateOfInspection列的数据类型是什么？听起来不应该是基于字符串的。

最后，您发布的错误消息听起来像来自SSRS而不是sql server。是这样的吗？您的查询是否可以从SSMS正确运行？然后问题出现在您的报告中 - 您似乎试图将Year列操作或解释为日期（可能用于排序？）。在您的报表设计中，您的“年份”列实际上是一个月的名称，并且您的结果集不以某种方式包含年份，这似乎也有点短视。当您的数据超过十二个月时会发生什么？如果您有月份名称而不是月份号，您打算如何对报告进行排序？

如何修复“从字符串转换”8月“到类型'日期'在SSRS中没有变化
