下面的查询正常工作:
SELECT
tblCase.ID AS CaseID, tblCase.UserID AS MyCasesFilter,
tblGroupMembership.UserID AS GroupShareFilter,
tblDirectCaseSharing.ReceiverUserID AS DirectShareFilter, tblCase.EntryDate,
tblUser.LastName AS CaseAuthor, tblCase.Name AS CaseName,
COUNT(DISTINCT tblCaseImage.ID) AS TotalImages,
tblCaseType.Name AS CaseType, tblCase.SiteName, tblCase.Category,
tblCase.FollowUpDateTime, tblCase.Notes
FROM
tblDirectCaseSharing
RIGHT OUTER JOIN
tblCase
INNER JOIN tblUser ON tblCase.UserID = tblUser.ID ON tblDirectCaseSharing.CaseID = tblCase.ID
LEFT OUTER JOIN
tblGroupMembership
INNER JOIN
tblGroupCase ON tblGroupMembership.GroupID = tblGroupCase.GroupID ON tblCase.ID = tblGroupCase.CaseID
LEFT OUTER JOIN
tblCaseType ON tblCase.CaseTypeID = tblCaseType.ID
LEFT OUTER JOIN
tblCaseImage ON tblCase.ID = tblCaseImage.CaseID
GROUP BY
tblCase.ID, tblCaseType.Name, tblCase.SiteName, tblCase.EntryDate,
tblCase.Category, tblCase.FollowUpDateTime, tblCase.Notes, tblCase.UserID,
tblGroupMembership.UserID, tblDirectCaseSharing.ReceiverUserID,
tblUser.LastName, tblCase.Name
HAVING
(tblCase.UserID = 1)
AND (tblGroupMembership.UserID = 2)
AND (tblDirectCaseSharing.ReceiverUserID = 3)
ORDER BY
tblCase.EntryDate DESC
我想使用一个select子查询向上面的结果中添加一个额外的select列,如下:
STUFF((
SELECT ', ' +tblGroup.Name as [text()]
FROM tblCase INNER JOIN
tblGroupCase ON tblCase.ID = tblGroupCase.CaseID INNER JOIN
tblGroup ON tblGroupCase.GroupID = tblGroup.ID
WHERE tblCase.ID = ***
FOR XML PATH('')
),1,2,'')
AS ConcatGroupShares
