连接表并获得COUNT

-1

我要总结一下我的模式和结果，我需要：连接表并获得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

结果，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

换句话说，每天，我需要得到每个状态的总数。

我这样做：

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，现在，但我认为这可能是一个有点草率。

这里是我的全部怪物查询此：

我真的不认为我应该做UNION ALL，而是构建一个更聪明的方式查询。你能帮我简化查询，这样我就不需要做UNION ALL了吗？

怎么样？

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个状态越多，你可以添加一个where子句来过滤。

我不认为你可以运行从union路程。记录位于不同的表格中，您需要从两个表格中获取它们。

而且它是一个union不是union all。后者将删除重复项，并将采取更多的执行。我们不needit因为有我写的查询，没有重复......我不能答应你的问题粘贴巨大的东西，任何东西：P

好主意!!!!!!现在我唯一想做的事情就是试着让最后一个UNION ALL从悬而未决。任何想法:) :) – 2012-02-26 19:53:24

我蒙蒂是这个，这是两个不同的表 - 最简单的（也可能是最快）的方式做到这一点是使用'UNION ALL'。这正是命令的目的。 – 2012-02-26 19:57:55

我的想法是你的工会在一个简单的CTE来源，然后有一个“怪物”查询：

; 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]
