我有一个复杂的 SQL 语句，我遇到了一个错误。他们提示我这个错误： GROUP BY 表达式中的错误。无法解析查询文本。

我粘贴了导致此错误的此 SQL 语句。谁能告诉我哪里出了问题？有任何想法吗？？？

如果您想这样做，只能在外部查询中选择聚合函数或分组列。您可以在分组依据中使用该列。

... GROUP BY AllocationDate, LocationName, StationName, Hour1, Hour2, Hour3, Hour4, Hour5, Hour6, Hour7, Hour8, Hour9, Hour10, Hour11, Hour12, EmpName, ShiftTime, BreakTime, SignIn, SignOut

谢谢。

我认为你混合了很多概念。如果没有 Min、Max、Avg 等聚合函数，您将无法使用 group by。

如果要使用 Group By，则必须说明如何处理这些非聚合字段：

Hour1, Hour2, Hour3, Hour4, Hour5, Hour6, Hour7, Hour8, Hour9, Hour10, Hour11, Hour12, EmpName, ShiftTime, BreakTime, SignIn, SignOut

我认为您想要的是 ORDER BY 而不是 GROUP BY。
