MSSQL横列转纵列

上篇我们说到了纵列转横列，这篇讲下横列转纵列，具体代码：

1.建表

CREATE TABLE [dbo].[EndLongChangeAcross](
    [Id] [int] IDENTITY(1,1) NOT NULL,
    [Name] [nvarchar](50) NOT NULL,
    [Chinese] [int] NOT NULL,
    [English] [int] NOT NULL,
    [Math] [int] NOT NULL,
 CONSTRAINT [PK_EndLongChangeAcross] PRIMARY KEY CLUSTERED
(
    [Id] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]

GO
SET IDENTITY_INSERT [dbo].[EndLongChangeAcross] ON 

GO
INSERT [dbo].[EndLongChangeAcross] ([Id], [Name], [Chinese], [English], [Math]) VALUES (1, N'张三', 89, 12, 82)
GO
INSERT [dbo].[EndLongChangeAcross] ([Id], [Name], [Chinese], [English], [Math]) VALUES (2, N'李四', 78, 45, 24)
GO
SET IDENTITY_INSERT [dbo].[EndLongChangeAcross] OFF
GO
ALTER TABLE [dbo].[EndLongChangeAcross] ADD  CONSTRAINT [DF_EndLongChangeAcross_Chinese]  DEFAULT ((0)) FOR [Chinese]
GO
ALTER TABLE [dbo].[EndLongChangeAcross] ADD  CONSTRAINT [DF_EndLongChangeAcross_English]  DEFAULT ((0)) FOR [English]
GO
ALTER TABLE [dbo].[EndLongChangeAcross] ADD  CONSTRAINT [DF_EndLongChangeAcross_Math]  DEFAULT ((0)) FOR [Math]
GO

2.具体SQL

SELECT  Name ,
        '语文' AS 'Subject',
        Chinese AS 'Score'
FROM    dbo.EndLongChangeAcross
UNION ALL
SELECT  Name ,
        '英语',
        English AS 'Score'
FROM    dbo.EndLongChangeAcross
UNION ALL
SELECT  Name ,
        '数学' ,
        Math AS 'Score'
FROM    dbo.EndLongChangeAcross
ORDER BY Name DESC

具体效果：
