尝试将以下语句从PL / SQL转换为T-SQL（正在进行的工作）。但是我在SQL Server中遇到了错误。

我在SQL Server中收到此错误。它很模糊。我在网上找到的资源并没有帮助我们理解这里的问题。

Msg 164, Level 15, State 1, Line 55
Each GROUP BY expression must contain at least one column that is not an 
outer reference.

*我添加了这句话，因为stackoverflow告诉我我的帖子主要是代码，我需要更多细节......

如果GROUP BY中有一个常量作为键，则会出现此错误。出于某种原因，这困扰着SQL Server。

在您的情况下，“常数”似乎是：

CONVERT(DATETIME, CONVERT(DATE, GETDATE()))

只需从GROUP BY键中删除它即可。

（并且，仅为了记录，每个查询对每个GETDATE()的引用进行一次评估，因此它是一个“常量”。）
