如何在SQL SERVER 2008 R2中连接两个或多个字符串？

Question

我希望连接两个或多个字符串，并在SQL Server 2008 R2中逐行显示在单个记录中。

我拥有的是，

shipsite|RatingMonth|Prior|Revised|Comments                    |
mopha   |Nov 2012   | 1   | 2     |rating.element.manual.asn   |
mopha   |Nov 2012   | 1   | 2     |rating.element.packaging    |
mopha   |Nov 2012   | 1   | 2     |rating.element.asn.accuracy |
mopha   |Nov 2012   | 1   | 2     |rating.element.over.shipment|
mopha   |Nov 2012   | 1   | 2     |rating.element.cum.imbalance|

我需要的是，

shipsite|RatingMonth|Prior|Revised|Comments                    |
mopha   |Nov 2012   | 1   | 2     |rating.element.manual.asn   |
        |           |     |       |rating.element.packaging    |
        |           |     |       |rating.element.asn.accuracy |
        |           |     |       |rating.element.over.shipment|
        |           |     |       |rating.element.cum.imbalance|

我不能在连接操作中使用任何逗号（，）或撇号（'）或没有特殊字符。所以你对此有任何想法。

SELECT shipsite, RatingMonth, Prior, Revised, Comments = STUFF((
  SELECT CHAR(13) + CHAR(10) + comments
    FROM dbo.YourTable AS x2 
      WHERE x2.shipsite = x.shipsite
      AND x2.RatingMonth = x.RatingMonth
      AND x2.Prior = x.Prior
      AND x2.Revised = x.Revised
    FOR XML PATH, TYPE).value('.[1]','nvarchar(max)'), 1, 2, '')
FROM dbo.YourTable AS x
GROUP BY shipsite, RatingMonth, Prior, Revised;
