Question

此查询为我提供了所需的所有信息，但是如果可能的话，我希望以不同的方式显示它。目前的结果：http://i.imgur.com/BFKGFSx.jpg

DECLARE @MainHospital varchar(50)='HOSPITAL 1';
SELECT MainEmail, chkOutpatient, chkPartB
FROM SurveyPicList
WHERE MainHospital = @MainHospital
GROUP BY MainHospital, MainEmail, chkOutpatient, chkPartB

我正在尝试返回2个不同的MainEmail comma-delimited列表，如果它们在chkOutpatient和chkPartB中为“on”。因此，结果只有2个数据单元。 chkOutpatient的1个标题，其中包含逗号稀释的电子邮件列表=“on”，以及chkPartB的1个标题。

那么对于chkPartB，这样的事情呢？http://i.imgur.com/RFlV24Q.jpg

SELECT DISTINCT ', ' + MainEmail AS chkPartB
FROM SurveyPicList
WHERE MainHospital = @MainHospital
AND chkPartB = 'on'

如果我的问题不清楚或者我是否需要提供更多信息，请告诉我。

WITH Outpatients AS (
    SELECT DISTINCT MainEmail
    FROM SurveyPicList
    WHERE MainHospital = @MainHospital
          AND chkOutpatient = 'on'
)
,OutpatientsRawCsv AS (
    SELECT (
       SELECT ',' + MainEmail
       FROM Outpatients
       FOR XML PATH('')
    ) AS Csv
)
,PartBs AS (
    SELECT DISTINCT MainEmail
    FROM SurveyPicList
    WHERE MainHospital = @MainHospital
          AND chkPartB = 'on'
)
,PartBRawCsv AS (
    SELECT (
       SELECT ',' + MainEmail
       FROM PartBs
       FOR XML PATH('')
    ) AS Csv
)
SELECT STUFF(OutpatientsRawCsv.Csv, 1, 1, '') AS OutpatientsCsv
      ,STUFF(PartBRawCsv.Csv, 1, 1, '') AS PartBCsv
FROM OutpatientsRawCsv
     CROSS JOIN PartBRawCsv
