如果您只是使用 SQL Server 2005/2008,则可以通过以下方式实现此目的。
declare @table table (
Code int,
Manager Varchar(1),
Employee varchar(10)
)
insert into @table values
(1,'A','Emp1'),
(1,'A','Emp2'),
(1,'A','Emp3'),
(2,'A','Emp4'),
(2,'A','Emp5')
select * from @table
select
case when number=1 then Code else null end as Code,
case when number=1 then Manager else null end as Manager,
employee
from (
select *,
row_number() over (partition by code, manager order by code,manager) as number
from @table
) x
这会给你:
(5 row(s) affected)
Code Manager Employee
----------- ------- ----------
1 A Emp1
1 A Emp2
1 A Emp3
2 A Emp4
2 A Emp5
(5 row(s) affected)
Code Manager employee
----------- ------- ----------
1 A Emp1
NULL NULL Emp2
NULL NULL Emp3
2 A Emp4
NULL NULL Emp5
(5 row(s) affected)
