我想使用 SQL Query RollUp 語句獲取示例輸出，因為性能是問題。 由於時間表表將有數百萬條記錄。 有沒有其他方法可以代替視圖來執行此編寫過程或函數？ 提前感謝您的幫助 Ishwor

我認為您不能將結果與同一個表中的數據混合。 另外，如果這是可能的，我認為這不是一個好主意。
您可以使用類似於此的查詢獲取小計：
select RosterID, EmpID, RosterDate, sum(Total)
from tableRoster group by RosterID, EmpID, RosterDate;
總數更容易，您可以通過以下方式獲得：
select sum(Total) from tableRoster;

我嘗試使用你喜歡的方法......盡管可能有一些問題需要解決。 如果它沒有像預期的那樣 100% 工作，請道歉，但也許您可以采用以下內容並根據您的需要對其進行修改。
我懷疑在那里包含開始/結束日期會導致可以忽略的微不足道的子分組。 我意識到不完全測試我的解決方案對於這個論壇來說並不理想......對此感到抱歉......只是一時興起，以分散工作的注意力。 祝你好運。
