SQL Server将多行数据合并为一行

一、引言

需求描述：现实工作中，有一些很特别的需求：在一个汇总表中，需要显示明细数据。因为是在汇总表中，所以明细数据只能显示在某一列中，这个列，就是多行数据合并为一行之后的结果。

案例描述：比如，在物料净需求表中，需求量扣减库存量、在途量等等之后，结果为剩余量，剩余量为负则需要采购。此时，不管剩余量为正还是为负，我们都需要密切关注在途量所涉及的采购单号，让物料在生产需求前到料并检验入库。假设在物料净需求表中，在途量明细需要显示为：采购单A，在途量：XXX；采购单B，在途量：XXX……以此类似，该如何处理呢？处理原理请往下看。

二、测试数据

CREATE TABLE [dbo].[Score]
(
    [ID] [varchar] (32) COLLATE Chinese_PRC_CI_AS NULL,
    [Name] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL,
    [Subject] [varchar] (20) COLLATE Chinese_PRC_CI_AS NULL,
    [Value] [numeric] (4, 1) NULL
) ON [PRIMARY]
GO
INSERT INTO SCORE ([ID],[NAME],[SUBJECT],[VALUE]) VALUES ("1001","张三","语文",86)
INSERT INTO SCORE ([ID],[NAME],[SUBJECT],[VALUE]) VALUES ("1001","张三","数学",88)
INSERT INTO SCORE ([ID],[NAME],[SUBJECT],[VALUE]) VALUES ("1002","李四","语文",89)
INSERT INTO SCORE ([ID],[NAME],[SUBJECT],[VALUE]) VALUES ("1002","李四","数学",90)

三、实现方法

3.1、STUFF函数

代码如下：

SELECT ID,[NAME],
    STUFF
    (
        (
            SELECT ","+[SUBJECT]+":"+CAST([VALUE] AS VARCHAR(MAX))
            FROM SCORE
            WHERE (ID=Result.ID)
            FOR XML PATH(""),TYPE).value("(./text())[1]","VARCHAR(MAX)"
        ),1,1,""
    ) AS NameValues
FROM SCORE Result
GROUP BY ID,[NAME]
ORDER BY ID

3.2、GROUP_CONCAT函数

GROUP_CONCAT并非SQL Server自带函数，本文使用的是来源于网络自由软件创建的托管代码。GroupConcatInstallation.sql为函数安装，GroupConcatUninstallation.sql为函数卸载。
