連接表並獲得COUNT

-1

我要總結一下我的模式和結果，我需要：連接表並獲得COUNT

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

結果，我需要：

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

換句話說，每天，我需要得到每個狀態的總數。

我這樣做：

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'

它的工作，現在，但我認爲這可能是一個有點草率。

這裏是我的全部怪物查詢此：

我真的不認爲我應該做UNION ALL，而是構建一個更聰明的方式查詢。你能幫我簡化查詢，這樣我就不需要做UNION ALL了嗎？

怎麼樣？

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

如果你有比在表A的2個狀態越多，你可以添加一個where子句來過濾。

我不認爲你可以運行從union路程。記錄位於不同的表格中，您需要從兩個表格中獲取它們。

而且它是一個union不是union all。後者將刪除重複項，並將採取更多的執行。我們不needit因爲有我寫的查詢，沒有重複......我不能答應你的問題粘貼巨大的東西，任何東西：P

好主意!!!!!!現在我唯一想做的事情就是試着讓最後一個UNION ALL從懸而未決。任何想法:) :) – 2012-02-26 19:53:24

我蒙蒂是這個，這是兩個不同的表 - 最簡單的（也可能是最快）的方式做到這一點是使用'UNION ALL'。這正是命令的目的。 – 2012-02-26 19:57:55

我的想法是你的工會在一個簡單的CTE來源，然後有一個「怪物」查詢：

; 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]
