insert into test_tab values (7)
insert into test_tab values (4)
insert into test_tab values (11)
insert into test_tab values (7)
insert into test_tab values (4)
insert into test_tab values (11)
insert into test_tab values (6)
insert into test_tab values (3)
insert into test_tab values (11)

查询:

;WITH cte as
(
SELECT *,((ROW_NUMBER() over(order by id)-1)/3)+1 as iden,
         ((ROW_NUMBER() over(order by id)-1)%3)+1 as ident  
FROM test_tab
)
SELECT max(case when iden = 1 then sophong end) as [1],
       max(case when iden =2 then sophong end) as [2],
       max(case when iden = 3 then sophong end) as [3]

FROM cte
group by ident

结果:

1   |2  |3
----+---+---
7   |7  |6
4   |4  |3
11  |11 |11
