根据结果使用 if 语句在查询中查询

Question

所以我有一个关于我创建的 SSRS 报告的特殊问题。

SELECT        rs.Name0, rs.User_Name0, rs.AD_Site_Name0, rs.User_Domain0, rs.Full_Domain_Name0, rs.Operating_System_Name_and0, eps.Active, eps.EpInstalled, eps.EpProtected, 
                         dbo.v_GS_AntimalwareHealthStatus.Enabled, dbo.v_GS_AntimalwareHealthStatus.Version, dbo.v_GS_AntimalwareHealthStatus.AntivirusEnabled, dbo.v_GS_AntimalwareHealthStatus.AntispywareEnabled, 
                         dbo.v_GS_AntimalwareHealthStatus.EngineVersion, eps.EpToBeInstalled,
                             (SELECT        rua.ProductName0
                               FROM            dbo.v_GS_CCM_RECENTLY_USED AS rua
                               WHERE        (rs.ressourceID = rua.ressourceID)) AS Kaspersky
FROM            dbo.v_R_System AS rs INNER JOIN
                         dbo.v_EndpointProtectionStatus AS eps ON rs.ResourceID = eps.ResourceID INNER JOIN
                         dbo.v_GS_AntimalwareHealthStatus ON rs.ResourceID = dbo.v_GS_AntimalwareHealthStatus.ResourceID INNER JOIN
                         dbo.v_GS_CCM_RECENTLY_USED_APPS AS rua ON rs.ResourceID = rua.ResourceID

为了快速起见，我正在尝试 select 如果计算机上启用了端点并且卡巴斯基也存在。但我想不通！我不知道如何管理它，因为这个查询：

(SELECT        rua.ProductName0
                               FROM            dbo.v_GS_CCM_RECENTLY_USED AS rua
                               WHERE        (rs.ressourceID = rua.ressourceID)) AS Kaspersky

它 return 多行（因为它们是在目标计算机集合上安装的多个版本的卡巴斯基。但我需要的是，如果它 return 是什么（因为这意味着卡巴斯基存在于机器上），那么 return 类似于“True”或“已安装”之类的东西。

我已经有一段时间没有做一些 SQL 查询了，所以如果你能帮助我，请先谢谢你。

所以我终于找到了答案，下面是这个：

SELECT      rs.Name0, 
            rs.User_Name0, 
            rs.AD_Site_Name0, 
            rs.User_Domain0, 
            rs.Full_Domain_Name0, 
            rs.Operating_System_Name_and0, 
            eps.Active, 
            eps.EpInstalled, 
            eps.EpProtected, 
            eps.EpToBeInstalled,

            Case WHEN EXISTS (SELECT rua.ProductName0 FROM v_GS_CCM_RECENTLY_USED_APPS AS rua WHERE rs.resourceID = rua.resourceID AND rua.ProductName0 LIKE '%Kaspersky%') 
            THEN 'Yes'
            ELSE 'No'
            END AS "Is Kaspersky installed?"

FROM            v_R_System AS rs INNER JOIN
                v_EndpointProtectionStatus AS eps ON rs.ResourceID = eps.ResourceID
