为什么
where.or( where.eq(foo.name, name) , where.isNull(foo.name) );
where.and();
where.and( where.eq(foo.foreign_id, foreign_id) , where.ne(foo.deleted , true) );
生成与
不同的结果集 where.and( where.eq(foo.foreign_id, foreign_id) , where.ne(foo.deleted , true) );
where.and();
where.or( where.eq(foo.name, name) , where.isNull(foo.name) );
？
