MSSQL如何聚合查詢中的行（非表）

Question

我需要在此查詢中將行聚合為字符串：

WITH requery AS 
    (SELECT  CAST ( Name AS VARCHAR(1000) ) as Folder, f1.ParentFolderID, unt.NetworkName, unt.Model, Marker
    FROM    [Base].[dbo].[Folders] as f1
    JOIN (
        SELECT u.NetworkName, m.Name as Model, u.ParentFolderID, ma.Name as Marker
        FROM Base.dbo.Units as u
            JOIN Base.dbo.Models as m
            ON u.ModelID=m.ModelID
            LEFT JOIN Base.dbo.MarkerLinks as ml
            ON u.ParentFolderID=ml.FolderID
            LEFT JOIN Base.dbo.MarkerS as ma
            ON ml.MarkerID = ma.MarkerID
        WHERE u.NetworkName LIKE 'pcname'   ) as unt ON unt.ParentFolderID = f1.FolderID
    UNION ALL
    SELECT  CAST ( (f.Name + '\' + f2.Folder) AS VARCHAR(1000) ) as Name, f.ParentFolderID, f2.NetworkName, f2.Model, f2.Marker
    FROM    [Base].[dbo].[Folders] f
    JOIN    requery as f2
    ON      f.FolderID = f2.ParentFolderID)
SELECT  NetworkName,Model,Folder,Marker
FROM    requery
WHERE ParentFolderID is NULL

它返回數據為

1. pcname型號位置user1
2. pcname型號位置user2
3. pcname型號位置user3

但是我需要

1. pcname型號位置user1，user2，user3

我知道OUTER APPLY（ 像那里 ），但是我不知道如何在這里使用它。 謝謝。

我＃$＃$＃，只是用此來查詢的最后一部分，它的工作！

SELECT  NetworkName,Model,Folder,Marker
FROM    requery
WHERE ParentFolderID is NULL
