鉴于我有这样的查询：

select employeeid as id, department as dep from employee where department in (...) 
order by department

我想要一个额外的列，每 3 个部门递增一次，以便结果看起来像这样：

id dep        magic
1  Accounting 0
30 Accounting 0
66 HR         0
67 HR         0
33 HR         0
2  Sales      0
9  IT         1
12 R&D        1
19 Design     1
45 QA         2
46 QA         2

我已经尝试过各种行号函数，over() 和其他巫术，但我似乎无法做到正确。希望你能帮我解决这个问题！

编辑：所以这并不像我希望的那样直截了当。上面的例子可能没有捕捉到我的案例中涉及的所有问题。所以这是我正在运行的真正查询：

select    sdi.sdcid
         ,sdi.keyid1
         ,sdi.paramlistid
         ,sdi.paramlistversionid
         ,sdi.variantid
         ,sdi.dataset
         ,sdi.paramid
         ,sdi.paramtype
         ,sdi.replicateid
         ,sd.sdidataid
        --(ROW_NUMBER() over(order by sd.sdidataid asc) -1) /3 partition
         from sdidataitem sdi
         left join sdidata sd on 
         sdi.keyid1 = sd.keyid1 
         and sdi.keyid2 = sd.keyid2 
         and sdi.keyid3 = sd.keyid3 
         and sdi.paramlistid = sd.paramlistid 
         and sdi.paramlistversionid = sd.paramlistversionid 
         and sdi.variantid = sd.variantid 
         and sdi.dataset = sd.dataset 
         where sd.sdidataid in (select top 30 sdidataid from sdidata) 
         and sdi.u_analysserieid is null
         order by sd.sdidataid asc

当我使用分区列运行查询时，出现以下错误：Cannot find either column "sd" or the user-defined function or aggregate "sd.sdidataid", or the name is ambiguous. 这是创建所涉及的两个表的代码：

您可以只使用 (ROW_NUMBER() OVER ...) / 3

select employeeid as id, department as dep , 
(row_number() over (order by department asc) -1) /3 partition
from employee 
where department in (...) 
order by department

关于您的查询。1）你似乎在第一个字段之后错过了逗号 2）如果你真的加入表格，最好使用 join，只是为了清楚起见

select sd.sdidataid, (ROW_NUMBER() over(order by sd.sdidataid asc) -1) /3 partition 
from sdidataitem sdi inner join sdidata sd on 
    sdi.keyid1 = sd.keyid1 (... more column restrictions) 
and sdi.dataset = sd.dataset 
where sd.sdidataid in (select top 30 sdidataid from sdidata) 
and sdi.u_analysserieid is null 
order by sd.sdidataid asc

Declare @tab table (id int,dep varchar(50))
insert into @tab Values(1,'Accounting'),(2,'Accounting'),(3,'Accounting'),(4,'AAA'),(5,'BBB'),(6,'ccc'),(7,'ddd'),(8,'eee'),(9,'fff');


Select t.*,a.Magic
from @tab t
join
(
Select dep,(ROW_NUMBER() over (order by dep) -1)/3 as Magic
from @tab
group by dep
) a on a.dep=t.dep
order by t.dep
