带有 COUNT() 语句的 SUM()

Question

我想知道是否可以在计数语句之后对特定值求和。 目前我有：

SELECT roles.Name AS Role_Name , COUNT(DISTINCT ur.UserId ) AS RoleCount FROM dbo.AbpUsers as users 
LEFT JOIN resourcing.CompanyorganizationUnitUserRole AS ur on users.Id = ur.UserId
LEFT JOIN dbo.AbpRoles AS roles ON roles.Id = ur.RoleId
GROUP BY roles.Name;

哪些输出：

Role_Name:                    |RoleCount:
TimeTrackingWritingMember     |8277
OrganizationUnitLeader        |529
Member                        |13901
DepartmentalCoordinator       |759
OrganizationUnitSecondLeader  |4
ResourceCoordinator           |6

这个想法是对例如 TimeTrackingWritingMember + Member = "Basic User"

的 roleCount 求和

我似乎不明白如何在一个查询中同时使用两者的逻辑。非常感谢所有帮助

您可以选择这两条记录的总和。

  SELECT SUM(A.ROLECOUNT) as 'Basic User'
    FROM(
        SELECT roles.Name AS Role_Name,
        COUNT(DISTINCT ur.UserId ) AS RoleCount 
        FROM dbo.AbpUsers as users 
        LEFT JOIN resourcing.CompanyorganizationUnitUserRole AS ur 
        on users.Id = ur.UserId
        LEFT JOIN dbo.AbpRoles AS roles ON roles.Id = ur.RoleId
        GROUP BY roles.Name;
        ) A 
    WHERE A.ROLE_NAME IN ('TimeTrackingWritingMember', 'Member')
