SQL - 2010 年仅进行过 dentry 检查的所有患者

Question

我有一个 T-SQL 查询，该查询为我提供了 2010 年最近一次就诊的信息，但不是 dentry 就诊。查询的相关部分是:

AND pv.PatientVisitId IN (                
    SELECT Max(pv1.PatientVisitID)            
        FROM PatientVisit pv1        
            JOIN DoctorFacility df1 ON pv1.FacilityID = df1.DoctorFacilityID
            JOIN PatientVisitResource pvr1 ON pv1.PatientVisitId = pvr1.PatientVisitId
                JOIN DoctorFacility dfr ON pvr1.ResourceId = dfr.DoctorFacilityId
        WHERE pv1.PatientProfileID = pp.PatientProfileID        
            AND pv1.Visit < '2011-01-01'    
            AND df1.ListName NOT LIKE '%Dental%'    
    )  

现在，我想扭转这一局面，为仅进行过 dentry 预约的患者获取最近的就诊信息。不过，我一直在这里碰壁。谁能带我到另一边吗？ :-)

线索是使用不存在的地方

AND pv.PatientVisitId IN (                
    SELECT Max(pv1.PatientVisitID)            
        FROM PatientVisit pv1        
            JOIN DoctorFacility df1 ON pv1.FacilityID = df1.DoctorFacilityID
            JOIN PatientVisitResource pvr1 ON pv1.PatientVisitId = pvr1.PatientVisitId
                JOIN DoctorFacility dfr ON pvr1.ResourceId = dfr.DoctorFacilityId
        WHERE pv1.PatientProfileID = pp.PatientProfileID        
            AND pv1.Visit < '2011-01-01'    
            AND df1.ListName LIKE '%Dental%'    
    ) 
and not exists ( Select 1 from   PatientVisit pv1        
            JOIN DoctorFacility df1 ON pv1.FacilityID = df1.DoctorFacilityID
            JOIN PatientVisitResource pvr1 ON pv1.PatientVisitId = pvr1.PatientVisitId
                JOIN DoctorFacility dfr ON pvr1.ResourceId = dfr.DoctorFacilityId
        WHERE pv1.PatientProfileID = pp.PatientProfileID        
            AND pv1.Visit < '2011-01-01'    
            AND df1.ListName NOT LIKE '%Dental%'    
    )
