Question

有人可以帮我这个子查询吗？

该表帐户的每个帐户都有customer id，account id和balance。

表客户具有customer id，customer city和customer type信息。

我想创建一个子查询，以显示单个客户的余额总和在5000到10000之间。

当我运行命令时，客户4,7和11的总余额结果实际上是所有客户的总和。

客户4的可用余额之和应为6,788。

17,0754是所有客户的总和。

哪里出问题了？

非常感谢您。

SELECT c.cust_id,c.cust_type_cd,c.city,sum(a.avail_balance)    
FROM customer c,account a
WHERE (SELECT sum(a.avail_balance)                                               
       FROM account a                                                                                
       WHERE a.cust_id = c.cust_id)                                                                           
BETWEEN 5000 AND 10000                                                                          
GROUP BY c.cust_id;

使用以下查询：

感谢您的帮助。确实在我将“ where”更改为“ having”并使用INNER JOIN之后。我设法解决了这个问题。这是更新的命令。只是想知道我们什么时候应该使用“ where”，什么时候应该使用“ having”？
