我想使用SQL Query RollUp语句获取示例输出，因为性能有问题。由于TimeSheet表将有数百万条记录。有没有其他方式来执行此编写过程或函数而不是视图？ 提前谢谢你的帮助 问候 Ishwor

我认为你不能将结果与同一个表中的数据混合在一起。 此外，如果这是可能的，我认为这不是一个好主意。
您可以使用与此类似的查询获取小计：
select RosterID, EmpID, RosterDate, sum(Total)
from tableRoster group by RosterID, EmpID, RosterDate;
总数更容易，你可以用它来获得它：
select sum(Total) from tableRoster;

我尝试使用您首选的方法......虽然可能会有一些问题需要解决。如果它没有像预期的那样100％工作，请道歉，但也许您可以采取以下措施并根据您的需要进行修改。
我怀疑在那里包括开始/结束日期将导致可以忽略的微不足道的子分组。我意识到没有完全测试我的解决方案对于这个论坛来说并不理想...对不起...只是一种随心所欲的鞭打它作为工作的快速分心。祝你好运。
