Sql server 使用汇总集和分组集格式化结果

sql-server sql-server-2008 sql-server-2008-r2

Sql server 使用汇总集和分组集格式化结果,sql-server,sql-server-2008,sql-server-2008-r2,Sql Server,Sql Server 2008,Sql Server 2008 R2,我正在尝试学习SQL Server 2008 R2中的汇总和分组集运算符。我的桌子看起来像这样： +-------+---------+------------+------+-------+----------+------+ | EmpID | EmpName | StartDate | Type | Units | Account | Dist | +-------+---------+------------+------+-------+----------+------+ | 1

我正在尝试学习SQL Server 2008 R2中的

汇总

和

分组集

运算符。我的桌子看起来像这样：

我是否可以使用

汇总

和/或

分组集

运算符来获得我想要的内容，而不是所有的

大小写

表达式？

我相信使用带有多维数据集的分组运算符将使您接近最终目标。使用这种方法，您可以选择过滤行或更改空值的显示方式

select 
    EmpID, 
    EmpName, 
    [Type], 
    Units, 
    Account
from 
    (   
        select 
            EmpID, 
            EmpName, 
            [Type], 
            sum(Units) AS Units, 
            Account
        from mytable
        group by EmpID, EmpName, [Type], Account with CUBE
    ) s

我相信使用多维数据集操作符的GROUP BY将使您接近最终目标。使用这种方法，您可以选择过滤行或更改空值的显示方式
