Присоединение к столам и получение COUNT

0 голосов
/ 26 февраля 2012

Я собираюсь обобщить мою схему и результат, который мне нужен: 

Table A(released and rejected):
day, specimenid, status,bunch of other unneeded fields....
1,AA123, released
1,AA132, released
2,BB234, rejected
3,BB444, released
3,AA444, rejected

Table B(pending):
day, specimenid, bunch of other unneeded columns
1, BB333
1, H234
2, C333
3, F333

Результат, который мне нужен: 

day, count, status
1, 2, released
1, 2, pending
2, 1, rejected
2, 1, pending
3, 1, released
3, 1, rejected
3, 1, pending

другими словами, за каждый день мне нужно получить общее количество для каждого статуса.

Я делаю это: 

select day, count(specimenid) from tableA where status='released', 'released'

union all

select day, count(specimenid) from tableA where status='rejected', 'rejected'

union all

select day, count(specimenid) from tableB, 'pending'

Пока это работает, но я думаю, что это может быть немного небрежно.

Вот мой полный запрос монстра для этого:

Я действительно не думаю, что должен делать UNION ALL, но вместо этого структурировать запрос более разумным способом. Не могли бы вы помочь мне упростить запрос, чтобы мне не нужно было выполнять UNION ALLs?

Как насчет? 

select day, count(*) as count, status from TableA
group by day, status
union
select day, count(*) as count, 'pending' from TableB
group by day

Если у вас есть больше, чем эти 2 статуса в Таблице A, вы можете добавить предложение where для их фильтрации.

Не думаю, что вы можетеубежать от union.Записи находятся в разных таблицах, и вам нужно получить их из обеих.

Также это union, а не union all.Последний удалит дубликаты и займет больше для выполнения.Нам это не нужно, потому что в запросах, которые я написал, нет дубликатов ... Я не могу ничего обещать об огромном материале, который вы вставили в вопрос: P

Моя мысль - объединить ваши источники в простой CTE, а затем получить один запрос «монстр»: 

; with cte as ( --union all for source rows without joins and clauses
    select * from A
    union all
    select *,'pending' from B
)
-- "monster" query without the union
select [day]
, [status]
, statusCount=COUNT(*)
from cte
group by [day], [status]
order by [day], [status]
