Question

我正在尝试在Access中加入查询和子查询，但是还没有关于如何执行此操作的最模糊的想法。而不是将子查询另存为其他查询，然后将其加入主查询。

主查询（参考子查询）：

SELECT tb200_IraDataIn.tb200_niarnum, tb206_IraAccount.tb206_IraAccDesc,
tb206_IraAccount.tb206_IraAccNum, tb15_Securities.tb15_IsActiveRegister,
tb15_Securities.tb15_NiarDesc, tb15_Securities.tb15_ManpikID, tb200_IraDataIn.tb200_Shovi, tb10_Afik.tb10_InvestTool, 
tb206_IraAccount.tb206_IsActive, tb200_IraDataIn.tb200_Shovi, 
tb200_IraDataIn.tb200_Shovi/SubQuery1.SumOftb200_Shovi AS Expr1
FROM SubQuery1 
     INNER JOIN (tb10_Afik 
         INNER JOIN (tb15_Securities 
           INNER JOIN (tb206_IraAccount 
              INNER JOIN tb200_IraDataIn 
              ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber) 
           ON tb15_Securities.tb15_NiarID = tb200_IraDataIn.tb200_niarnum) 
         ON (tb10_Afik.tb10_AfikID = tb200_IraDataIn.tb200_afik) AND (tb10_Afik.tb10_Erp =tb200_IraDataIn.tb200_ERP))
     ON SubQuery1.tb206_IraAccNum = tb206_IraAccount.tb206_IraAccNum
WHERE (((tb15_Securities.tb15_IsActiveRegister)=Yes) AND ((tb10_Afik.tb10_InvestTool)=1
Or (tb10_Afik.tb10_InvestTool)=4 Or (tb10_Afik.tb10_InvestTool)=21 Or 
(tb10_Afik.tb10_InvestTool)=3) AND ((tb206_IraAccount.tb206_IsActive)=Yes) AND 
(([tb200_IraDataIn].[tb200_Shovi]/[SubQuery1].[SumOftb200_Shovi])>0.1));

子查询（保存为SubQuery1）：

SELECT tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum, Sum(tb200_IraDataIn.tb200_Shovi) AS SumOftb200_Shovi
FROM tb206_IraAccount 
INNER JOIN tb200_IraDataIn ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber
WHERE (((tb206_IraAccount.tb206_IsActive)=Yes))
GROUP BY tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum;

与现在不同，如何将子查询的sql语句放入主查询的同一sql语句中？

谢谢！

Answer 1

括号之间的嵌套。主查询中的其他内容都没有改变。

SELECT
...
FROM (SELECT tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum, Sum(tb200_IraDataIn.tb200_Shovi) AS SumOftb200_Shovi
FROM tb206_IraAccount 
INNER JOIN tb200_IraDataIn ON tb206_IraAccount.tb206_IraAccNum = tb200_IraDataIn.tb200_accountNumber
WHERE (((tb206_IraAccount.tb206_IsActive)=Yes))
GROUP BY tb206_IraAccount.tb206_IraAccDesc, tb206_IraAccount.tb206_IraAccNum) AS SubQuery1
...

联接查询和子查询
