SQL Server：修改此查詢

Question

此查詢爲我提供了所需的所有信息，但我希望以不同的方式顯示它。目前的結果是：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 

我試圖返回MainEmail comma-delimited 2個不同的列表，如果他們在chkOutpatient和chkPartB = 「ON」。所以只有2個數據單元。 chkOutpatient的1個標題，其中包含逗號分隔的電子郵件列表，其中=「on」，以及chkPartB的1個標題相同。

所以對於chkPartB，這樣的事情？ http://i.imgur.com/RFlV24Q.jpg

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

請讓我知道，如果我的問題不清楚，或者如果我需要提供更多的信息。
