Question

我想知道将以下行中的数据合并到另一个视图中的单个行的最佳方法。

这些是当前显示的结果;

 Type_ID | Client_ID              | PBX_Vendor |
 127     | 090820006311404926326C | Aastra     |
 127     | 090820006311404926326C | Ericsson   |
 127     | 111012237401404926326C | Aastra     |
 127     | 120209287521404926326C | Aastra     |
 127     | 120209287521404926326C | Alcatel    |

以下是我希望看到的数据;

 Type_ID | Client_ID              | PBX_Vendor       |
 127     | 090820006311404926326C | Aastra, Ericsson |
 127     | 111012237401404926326C | Aastra           |
 127     | 120209287521404926326C | Aastra, Alcatel  |

基本上，有多个PBX供应商与客户端ID相关联。对于服务台系统，我需要在一行中显示这个显示。

我已经尝试过使用CONCAT了，但我最终得到的只是一行，其中有超过100个供应商并非特定于Client_ID。

非常感谢任何帮助！

这是 A 的方法（也适用于2005年）：

表格

DECLARE @table TABLE ( [Type_ID] INT, [Client_ID] VARCHAR(50), [PBX_Vendor] VARCHAR(50) )

数据

INSERT INTO @table SELECT 127, '090820006311404926326C', 'Aastra' UNION ALL SELECT 127, '090820006311404926326C', 'Ericsson' UNION ALL SELECT 127, '111012237401404926326C', 'Aastra' UNION ALL SELECT 127, '120209287521404926326C', 'Aastra' UNION ALL SELECT 127, '120209287521404926326C', 'Alcatel'

<强>查询

SELECT [Type_ID], [Client_ID], ( SELECT STUFF(( SELECT ',' + [PBX_Vendor] FROM @table WHERE [Client_ID] = tbl.[Client_ID] AND [Type_ID] = tbl.[Type_ID] GROUP BY [PBX_Vendor] ORDER BY [PBX_Vendor] FOR XML PATH('') ), 1, 1, '') ) PBX_Vendor FROM @table tbl GROUP BY [Type_ID], [Client_ID]

<强>结果

Type_ID Client_ID PBX_Vendor 127 090820006311404926326C Aastra,Ericsson 127 111012237401404926326C Aastra 127 120209287521404926326C Aastra,Alcatel

丹，我已经设法通过一些修改使用你原来的想法。虽然我无法将其保存为视图，因为据我所知，您无法将DECLARES保存为VIEWS;

DECLARE @table TABLE
    (
      [Type_ID] INT,
      [Client_ID] VARCHAR(50),
      [PBX_Vendor] VARCHAR(50)
    )

INSERT  INTO @table
        SELECT  dbo.AMGR_User_Fields_Tbl.Type_Id, dbo.AMGR_User_Fields_Tbl.Client_Id, dbo.AMGR_User_Field_Defs_Tbl.Description AS PBX_Vendor
            FROM    dbo.AMGR_User_Fields_Tbl INNER JOIN
                    dbo.AMGR_User_Field_Defs_Tbl ON dbo.AMGR_User_Fields_Tbl.Type_Id = dbo.AMGR_User_Field_Defs_Tbl.Type_Id AND 
                    dbo.AMGR_User_Fields_Tbl.Code_Id = dbo.AMGR_User_Field_Defs_Tbl.Code_Id
            WHERE     (dbo.AMGR_User_Fields_Tbl.Type_Id = 127)

SELECT  [Type_ID],
        [Client_ID],
        (
          SELECT    STUFF((
                            SELECT  ', ' + [PBX_Vendor]
                            FROM    @table
                            WHERE   [Client_ID] = tbl.[Client_ID]
                                    AND [Type_ID] = tbl.[Type_ID]
                            GROUP BY [PBX_Vendor]
                            ORDER BY [PBX_Vendor]
                          FOR
                            XML PATH('')
                          ), 1, 1, '')
        ) PBX_Vendor
FROM    @table tbl
GROUP BY [Type_ID],
        [Client_ID]

将多行合并为一行
