Question

我有一个独特的要求，我有3个审计表，任何时候进行更改都会为更改创建新记录。现在我需要创建一个视图，它将获得不同的订单ID以及在3个受尊重的表中更改它们的次数。

这是我开发的SQL

select  distinct orderid as salesorderid,COUNT (*) AS SALESORDERUPDATE  
FROM  foobar 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by Orderid
union all 
select  distinct orderid as salesorderid,count(*)  SALESORDERUPDATE  AS   
from foobar1 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by OrderID
union all
select distinct orderid as salesorderid,count(*)AS SALESORDERUPDATE  
from foobar2 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by  Orderid;

现在我得到的结果是这样的对于orderid 1，我有3个条目显示count（*）的不同值。我想在一行中总结一下

所以它会像

orderid  123  salesorderupdate(20) 
as suppose to 
orderId 123 salesorderupdate(10)
orderid 123 salesorderupdate(7)
orderid 123 salesorderupdate(3)

谢谢，

Answer 1

像这样：

 select orderID, sum(salesorderupdate)
 from 
 (the query from your question goes here) temp
 group by orderId

Answer 2

使您的查询成为子表，然后选择id和总和

select distinct orderid, sum(SALESORDERUPDATE)
from (
select  distinct orderid as salesorderid,COUNT (*) AS SALESORDERUPDATE  
FROM  foobar 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by Orderid
union all 
select  distinct orderid as salesorderid,count(*)  SALESORDERUPDATE  AS   
from foobar1 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by OrderID
union all
select distinct orderid as salesorderid,count(*)AS SALESORDERUPDATE  
from foobar2 
where ModifiedDateTime>'2015-11-01 20:44:55.107' group by  Orderid;
) changes group by orderid;

用于计算记录更改次数的SQL语句
