GROUP BY子句中的錯誤。 無法解析查詢文本

Question

我有一個復雜的SQL語句，但遇到錯誤。 他們提示我這個錯誤：GROUP BY表達式中的錯誤。 無法解析查詢文本。

我粘貼了導致此錯誤的此SQL語句。 誰能告訴我哪里出了問題？ 有任何想法嗎？？？

Answer 1

我認為您正在混合很多概念。 沒有最小，最大，平均等聚合功能，您將無法使用分組依據。

如果要使用分組依據，則必須告訴如何處理這些非聚合字段：

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

我認為您想要的是ORDER BY，而不是GROUP BY。

Answer 2

如果要執行此操作，則只能在外部查詢中選擇聚合函數或分組的列。 您可以在分組依據中使用該列。

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

謝謝。
