GRAILS中Criteria的OR的写法

Person.withCriteria {
    or {
        and {
            eq 'lastName', 'Winter'
            eq 'firstName', 'Johnny'
        }
        and {
            eq 'lastName', 'Brown'
            eq 'firstName', 'Jeff'
        }
    }
}

 

上面的语言将对应如下SQL语句

 

 

 

select
    this_.id as id0_0_,
    this_.version as version0_0_,
    this_.last_name as last3_0_0_,
    this_.first_name as first4_0_0_
from
    person this_
where
    (
        (
            this_.last_name='Winter'
            and this_.first_name='Johnny'
        )
        or (
            this_.last_name='Brown'
            and this_.first_name='Jeff'
        )
    )
