我正在尝试提取患者列表，并且需要排除所有重复的 SubscriberNumber 值。我可以在没有 Where (Primary_Insurance.SubscriberNumber = 的情况下使用 Select Distinct 子句，它工作正常。当我将 (Primary_Insurance.SubscriberNumber = 添加到我的查询中时，它会忽略我的日期范围并提取与 SubscriberNumber 关联的所有约会

SELECT   Primary_Insurance.SubscriberNumber,  Encounter.DTTM, Patient_Iorg.OrganizationMrn AS MRN, Patient_Contact.HomePhoneArea, Patient_Contact.HomePhoneExchange, Patient_Contact.HomePhoneLast4, 
         Patient_Contact.LastName, Patient_Contact.FirstName, Patient_Contact.AddressLine1, Patient_Contact.AddressLine2, Patient_Contact.City, Patient_Contact.State, Patient_Contact.Zip, 
         Appointment.AppointmentStatusDE
FROM            Appointment INNER JOIN
                     Encounter ON Appointment.PatientID =   Encounter.PatientID INNER JOIN
                     Patient_Iorg INNER JOIN
                     Patient_Contact ON Patient_Iorg.PersonID = Patient_Contact.PatientID INNER JOIN
                     Primary_Insurance ON Patient_Iorg.PersonID = Primary_Insurance.patientid ON Encounter.PatientID = Primary_Insurance.patientid
WHERE           (Encounter.DTTM > CONVERT(DATETIME, '2018-06-15 00:00:00', 102)) AND (Encounter.DTTM >= CONVERT(DATETIME, '2018-12-31 00:00:00', 102)) AND (Appointment.AppointmentStatusDE = 4) AND 
                     (Primary_Insurance.SubscriberNumber = '19803782') OR
                     (Primary_Insurance.SubscriberNumber = '19835428') OR
                     (Primary_Insurance.SubscriberNumber = '19914818') OR
                     (Primary_Insurance.SubscriberNumber = '19993082') OR
                     (Primary_Insurance.SubscriberNumber = '19993082') OR
                     (Primary_Insurance.SubscriberNumber = '19993082')
group BY             Primary_Insurance.SubscriberNumber, Encounter.DTTM, Patient_Iorg.OrganizationMrn, Patient_Contact.HomePhoneArea, Patient_Contact.HomePhoneExchange, Patient_Contact.HomePhoneLast4, 
                     Patient_Contact.LastName, Patient_Contact.FirstName, Patient_Contact.AddressLine1, Patient_Contact.AddressLine2, Patient_Contact.City, Patient_Contact.State, Patient_Contact.Zip, 
                     Appointment.AppointmentStatusDE;

需要弄清楚如何将 Distinct 与多个 Where 子句和内连接一起使用

大概，您打算的逻辑是：

WHERE Encounter.DTTM > '2018-06-15' AND 
      Encounter.DTTM >= '2018-12-31' AND
      Appointment.AppointmentStatusDE = 4 AND 
      Primary_Insurance.SubscriberNumber IN ('19803782', '19835428', '19914818', '19993082', '19993082', '19993082')

您的查询有问题，因为OR条件周围没有括号。但是，不是使用括号，IN而是更简单、更清晰。

请注意，我更改了日期常量。SQL Server 非常擅长将值转换为日期。我觉得这更具可读性。
