非重复的多个 SQL 记录我无法摆脱

Question

我正在尝试生成一份报告，以显示哪些用户被限制在特定设施中。我使用的基本代码是：

 `SELECT DISTINCT ppp.DeptID,
        mis.UserID,
        mis.[Name],
        CASE 
            WHEN mis.ProviderID IS NULL
                THEN 'No'
            ELSE 'YES'
            END AS 'IsProv',
        CASE 
            WHEN af.FacilityID = 'PSY'
                THEN 'Restricted'
            ELSE 'Not Restricted'
            END AS 'SignOnFacility',
        CASE 
            WHEN fr.FacilitiesRestrictedID = 'PSY'
                THEN 'Restricted'
            ELSE 'Not Restricted'
            END AS 'FacilityToRestrict',
        mis.Active
    FROM DMisUsers mis
    LEFT JOIN DMisUserRestrictedAdmMriFac fr
        ON mis.UserID = fr.UserID
            AND mis.SourceID = fr.SourceID
    LEFT JOIN DMisUserAdmMriFacility af
        ON af.UserID = mis.UserID
    INNER JOIN PpEmployees pe
        ON mis.SourceID = pe.SourceID
            AND mis.UserID = pe.UserID
    INNER JOIN PpPayrollPosition ppp
        ON ppp.EmployeeID = pe.EmployeeID
            AND pe.SourceID = ppp.SourceID
    WHERE mis.SourceID = 'STP'
        AND mis.Active = 'Y'`

这会产生以下结果集，该结果集为每个“设施”列带来一行。

 | DeptID | UserID  |IsProv| SignOnFacility | FacilityToRestrict | Active|
 |01.9030 | PPaul   |   No | Not Restricted | Not Restricted     | Y     |
 |01.9030 | PPaul   |   No | Not Restricted | Restricted         | Y     |

我想要做的是得到一个像这样的单行：

 | DeptID | UserID  |IsProv| SignOnFacility | FacilityToRestrict | Active|
 |01.9030 | PPaul   |   No | Not Restricted | Restricted         | Y     |

我尝试过 CTE、使用 Row_Number() 绕过聚合的枢轴以及其他几种方法。任何帮助将不胜感激。

我很确定你想要group by。这是我对逻辑的猜测：

SELECT ppp.DeptID, mis.UserID, mis.[Name],
       COALESCE(MAX(CASE WHEN mis.ProviderID IS NOT NULL THEN 'YES' END), 'NO') as IsProv,
       COALESCE(MAX(CASE WHEN af.FacilityID <> 'PSY' THEN 'Not Restricted' END), 'Restricted') as SIgnOnFacility,
       COALESCE(MAX(CASE WHEN fr.FacilitiesRestrictedID <> 'PSY' THEN 'Not Restricted' END) as FacilityToRestrict,
        mis.Active
FROM . . .
GROUP BY ppp.DeptID, mis.UserID, mis.[Name], mis_Active;
