将两个查询合并为一个

Question

在访问中-我想显示一个查询，它为用户提供这两个查询的结果，因此查询结果为状态，CountOfSP，CountOfUsers

当前要获取信息，我们运行两个单独的查询

Select State, Count(userID) As CountOfUsers
From SalesData
Group By State
Order By State;

然后我们的第二个查询是

Select [%$##_Alias].State, Count(salesPerson) As CountOfSalesPerson
From 
(
  Select distinct salesPerson, State
  From salesData
) AS [%$##@_Alias]
Group By [%$##@_Alias].State

Access sql中是否有一种方法可以组合这两个查询，以便我可以从一个查询中获取所有我需要的数据？

编辑我尝试了这种语法，但是它给了我很大的数字，并且CountOfUsers和CountOfSalesPerson的计数完全相同

SELECT salesData.State, Count(salesData.userID) AS CountOfUsers, C 
ount(Regioninfo.salesPerson) AS CountOfSalesPerson
FROM salesData 
LEFT JOIN 
(
    Select distinct salesPerson, State
    From salesData
    group by Region, salesPerson
)  AS Regioninfo ON salesData.State = Regioninfo.State
GROUP BY salesData.State

ORDER BY salesData.State;

Answer 1

您可以像这样加入他们：

Select State, Count(userID) As CountOfUsers, Count(stateinfo.salesPerson) As CountOfSalesPerson
From SalesData
left join (
  Select distinct salesPerson, State
  From salesData
  group by state
) AS stateinfo on statedata.state = stateinfo.state
Group By Region
Order By Region;

Answer 2

;with t as
(
    Select [%$##_Alias].State, Count(salesPerson) As CountOfSalesPerson
    From 
    (
        Select distinct salesPerson, State
        From salesData
    ) AS [%$##@_Alias]
    Group By [%$##@_Alias].State
)

Select State, Count(userID) As CountOfUsers, t.CountOfSalesPerson
From SalesData s
left join t on t.state = s.state
Group By Region
Order By Region;
