Increment SQL столбец на основе другого

Question

Учитывая, что у меня есть запрос, как это:

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

Я хотел бы иметь дополнительный столбец, который увеличивает на каждые 3 отделов, так что результат выглядит примерно так:

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 

Я пробовал с различными функциями номера ряда, над() и другим вуду, но я не могу понять, как это правильно. Надеюсь, ты поможешь мне с этим!

Редактировать: Так что это было не так прямо, как я надеялся. В приведенном выше примере, вероятно, не было зафиксировано все проблемы, связанные с моим делом. Так что это реальный вопрос, что я бегу:

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  

при запуске запроса с колонки раздела я получаю следующее сообщение об ошибке: Cannot find either column "sd" or the user-defined function or aggregate "sd.sdidataid", or the name is ambiguous. Это код, чтобы создать две таблицы участвуют:

Answer 1

Вы можете просто использовать (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 

О запросе. 1) Вы, кажется, пропустить запятую после первого поля 2) более эффективное использование присоединиться, если вы на самом деле объединение таблиц, просто для ясности

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 

Answer 2

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
