Question

我有以下Nhibernate LINQ查询：

var query = from c in session.Query<Customer>()
            where
                c.EmailAddress == customer.EmailAddress ||
                (
                    c.Address1 == customer.Address1 &&
                    c.City == customer.City &&
                    c.State == customer.State &&
                    c.Postal == customer.Postal &&
                    c.FirstName == customer.FirstName &&
                    c.LastName == customer.LastName
                )
                select c;

我希望生成的SQL语句看起来像：

select
    ...
from
    dbo.Customers customer0_ 
where
    customer0_.EmailAddress=@p0 or 
    (
        customer0_.Address1=@p1 
        and customer0_.City=@p2 
        and customer0_.State=@p3 
        and customer0_.Postal=@p4 
        and customer0_.FirstName=@p5 
        and customer0_.LastName=@p6;
    )

但是我从调试日志中看到的是：

select
    ...
from
    dbo.Customers customer0_ 
where
    customer0_.EmailAddress=@p0 
    or customer0_.Address1=@p1 
    and customer0_.City=@p2 
    and customer0_.State=@p3 
    and customer0_.Postal=@p4 
    and customer0_.FirstName=@p5 
    and customer0_.LastName=@p6;

请注意，where子句的地址部分没有分组。这是故意的吗？我应该以不同的方式格式化我的查询，还是这是一个错误？

Answer 1

生成的SQL是正确的;不需要括号。

使用LINQ的NHibernate 3.1嵌套where子句不能创建正确的SQL
