语法错误缺少表达

Question

您好，我想显示所有客户的名称，这些客户在银行的任何分支机构中只有一个账户余额超过$ 1000的帐户，而在Edina的任何分支机构中只有一笔或多于$ 4000的贷款

select account.cname, 
from Account
where account.bal > 1000
UNION
(select loan.cname
 from loan
 where loan.amt>4000 AND
    l.bname )in (
        select bname
        from branch
        where lower(bcity)= 'edina'
    );

看起来不错吗？

Answer 1

您在第一次选择时要使用逗号。 您的in子句没有要与之比较的列

也许是这样的：

select account.cname
from Account 
where account.bal > 1000 
UNION 
select loan.cname 
from loan 
where loan.amt>4000 AND l.bname 
and loan.bname in ( select bname from branch where lower(bcity)= 'edina' )
