Question

我正在尝试将列中的某些值连接到单个字段中。

到目前为止，我有以下代码。

SELECT DISTINCT [customer id]
      ,[customer name]
      ,STUFF( (SELECT ',' + [description] 
                             FROM [Invoicing].[dbo].[CurrentBillMaster] 
                             ORDER BY [description]
                             FOR XML PATH('')),
                            1, 1, '')
      ,[id]
      ,[Section]
      ,[customerpo]
  FROM [Invoicing].[dbo].[CurrentBillMaster]
  GROUP BY [customer id], [customer name], [description],[qty],
           [identifier],[FromDate],[ToDate],[id],[Section],[customerpo]

代码很大程度上有效，但是我想要连接描述，只是为了显示该唯一[客户ID]的描述

任何帮助非常感谢

您需要关联子查询：

SELECT  [customer id]
      ,[customer name]
      ,STUFF( (SELECT ',' + [description] 
                             FROM [Invoicing].[dbo].[CurrentBillMaster] t
                             WHERE  t.Customer_id = c.customer_id  -- here
                             ORDER BY [description]
                             FOR XML PATH('')),
                            1, 1, '')
      ,[id]
      ,[Section]
      ,[customerpo]
  FROM [Invoicing].[dbo].[CurrentBillMaster] c
  GROUP BY [customer id], [customer name], [description],[qty],
           [identifier],[FromDate],[ToDate],[id],[Section],[customerpo]

分组为XML Path ibn SQL
