在父表中选择计数

问题描述

我在ms访问中有两个表（表一是父表，表二是子表）与ID相关

表一：

表二：

我需要一个选择的 sql 代码来运行这个查询：

我可以在不计算 TeamName 的情况下编写 sql 命令：

Select Table1.TackName,Sum(Table2.PaintingValue) as SumofPaintingValue
from (Table1 INNER JOIN
      Table2
      on (Table1.ID = Table2.fgk)
GROUP BY Table1.TackName 

解决方法

试试这个

Select TrackName,Sum(PaintingValue) as SumOfPaintingValue,Dcount( "TrackName","Table1","TrackName='" & a.TrackName & "'") as CountOfTeamName   from Table1 as a INNER JOIN Table2  as b ON a.ID = b.fgk
group by TrackName

或

创建两个保存的查询

qryA

Select TrackName,count(TrackName) as CountOfTeamName from Table1 as a group by TrackName

qryB

Select TrackName,Sum(PaintingValue) as SumOfPaintingValue from Table1 as a INNER JOIN Table2 as b ON a.ID = b.fgk group by TrackName

然后使用下面的结果

Select qryA.TrackName,SumOfPaintingValue,CountOfTeamName from qryA INNER JOIN qryB on qryA.TrackName = qryB.TrackName

,

我目前无法对此进行测试，但我认为相关查询应该可以解决问题：

Select 
Table1.TackName,Sum(Table2.PaintingValue) as SumofPaintingValue,(select count(TeamName) from table1 t1 where t1.TrackName=table1.TrackName
group by TeamName) as CountOfTeams
from Table1 INNER JOIN Table2 on (Table1.ID = Table2.fgk) 
GROUP BY Table1.TackName
