MySQL的RIGHT JOIN嵌套子查询

我有一个右下面的查询上的“C”我subequery加入MySQL的RIGHT JOIN嵌套子查询

$sqlbsc="SELECT customers.LastName, Sum(IFNULL(scripts.PharmAmount,0)) AS SumPharm, customers.ChemistID, customers.FullName 

    FROM 

    (SELECT scripts.WrittenOff, scripts.PharmAmount, scripts.ChemistID, scripts.ReconcilID, claims.CustomerID FROM scripts 

    INNER JOIN 

    claims ON scripts.ClaimID = claims.ClaimID 

    WHERE 

    (((scripts.WrittenOff)=False) AND ((scripts.ChemistID)='".$_SESSION['chsh']."') AND ((scripts.ReconcilID) IS NULL))) c 

    RIGHT JOIN customers ON c.CustomerID = customers.CustomerID 

    GROUP BY customers.LastName, customers.ChemistID, customers.FullName 

    HAVING ((customers.ChemistID)='".$_SESSION['chsh']."') 

    ORDER BY customers.LastName";

这是

Customers.FirstName, Customers.LastName and Sum(Scripts.pharmamount) where Scripts.reconcilID IS NULL

结束了，但我想我所有的客户从我的客户表中出现，并且只显示为sum = $0.00

我有工作在Ms Access作为子查询，但上面没有给我什么。

我的结果对于我的子查询SQL是正确的。当我使用它它的作品，但我的主要查询不起作用。

任何人都可以提供一些见解吗？

修好了!!! 2小时..然后张贴在这里，我修复了我自己在1分钟大声笑我需要更改scripts.pharmamount c.pharmamount，因为它指的是子查询不是实际的表！

最终的查询非常相似：

$sqlbsc="SELECT customers.LastName, Sum(IFNULL(c.PharmAmount,0)) AS SumPharm, customers.ChemistID, customers.FullName 

FROM 

(SELECT scripts.WrittenOff, scripts.PharmAmount, scripts.ChemistID, scripts.ReconcilID, claims.CustomerID FROM scripts 

INNER JOIN 

claims ON scripts.ClaimID = claims.ClaimID 

WHERE 

(((scripts.WrittenOff)=False) AND ((scripts.ChemistID)='".$_SESSION['chsh']."') AND ((scripts.ReconcilID) IS NULL))) c 

RIGHT JOIN customers ON c.CustomerID = customers.CustomerID 

GROUP BY customers.LastName, customers.ChemistID, customers.FullName 

HAVING ((customers.ChemistID)='".$_SESSION['chsh']."') 

ORDER BY customers.LastName";
