--> 测试数据：[huang]
if object_id('[huang]') is not null drop table [huang]
go
create table [huang]([ID] int,[姓名] varchar(4),[课程] varchar(4),[分数] int)
insert [huang]
select 1,'张三','语文',77 union all
select 2,'张三','数学',88 union all
select 3,'张三','英语',99 union all
select 4,'李四','语文',75 union all
select 5,'李四','数学',85

declare @s nvarchar(4000)
set @s=''
Select @s=@s+','+quotename([课程])+'=max(case when [课程]='+quotename([课程],'''')+' then [分数] else null end)'
from [huang] WHERE [姓名]='李四' group by [课程]
exec('select row_number()over(order by getdate()) as id,[姓名]'+@s+' from [huang] where [姓名]=''李四'' group by [姓名]')
----------------结果----------------------------
/*
id 姓名 数学 语文
-------------------- ---- ----------- -----------
1 李四 85 75
*/
这个行转列后，列名默认是按照首字母排序的吧，那如何不按照首字母排序，直接按照原表的顺序，使其得到的结果如下
----------------结果----------------------------
/*
id 姓名 语文 数学
-------------------- ---- ----------- -----------
1 李四 75 85

from [huang] WHERE [姓名]='李四' group by [课程] ORDER BY MIN(ID)
exec('select row_number()over(order by getdate()) as id,[姓名]'+@s+' from [huang] where [姓名]=''李四'' group by [姓名]')加个排序即可
