Sql server 转换多列

我的表格包含一些数据：

DECLARE @temp TABLE (id INT, name VARCHAR(20), [INDEX] INT, [GROUP] INT)

INSERT INTO @temp (id, name, [INDEX], [GROUP])

这就是我想要的结果

如图所示，如何从表1查询到表2？

下面的查询完成了这项工作

declare @tab1 table (id INT, name VARCHAR(20), [INDEX] INT, [GROUP] INT)
declare @tab2 table (id INT, name VARCHAR(20), [INDEX] INT, [GROUP] INT)
declare @tab3 table (id INT, name VARCHAR(20), [INDEX] INT, [GROUP] INT)

insert into @tab1 
    select *  from testtab where [group] =1

insert into @tab2 
    select *  from testtab where [group] =2

insert into @tab3 
    select *  from testtab where [group] =3

select * 
from @tab1 a 
right join @tab2 b on a.[index] = b.[index]  
left join @tab3 c on a.[index] = c.[index] 
order by b.[index]

你需要试一试，让我们看看你的尝试。我以前考虑过，但我只提供一些数据。事实上，将会有更多的团体，我无法确定哪一个团体更多
