Question

I have the following Nhibernate LINQ query:

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;

I expected the resulting SQL statement to look like:

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;
    )

But what I see from the debug log is:

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;

Notice there is no grouping on the address part of the where clause. Is this intentional? Should I be formatting my query a different way, or is this a bug?

Answer 1

The generated SQL is correct; the parentheses are not needed.
