如何在 SQL SERVER 2008 R2 中连接两个或多个字符串？

Question

我想连接两个或多个字符串，并在 SQL Server 2008 R2 中逐行显示在一条记录中。

我所拥有的是，

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。那么你对此有什么想法吗？

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(N'/text().[1]', N'nvarchar(max)'), 1, 2, N'')
FROM dbo.YourTable AS x
GROUP BY shipsite, RatingMonth, Prior, Revised;
