Question

我有一个复杂的SQL语句，我犯了一个错误。他们提示我这个错误：GROUP BY表达式出错。无法解析查询文本。

我粘贴了这个导致此错误的SQL语句。任何人都可以告诉我哪里出错了？任何想法???

Answer 1

我认为你混合了很多概念。如果没有Min，Max，Avg等聚合函数，则不能使用组

如果您想使用分组依据，您必须告诉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

我认为你想要的是一个ORDER BY而不是GROUP BY。

Answer 2

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group by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
