如何在mysql中对数据类型tiny int进行排序

我需要什么

• 我需要对mysql中的整数进行排序

取消订阅tinyint（6）

1,1,4,5,1,1等

sql查询

 SELECT e0_.metadata AS metadata0, u1_.unsubscribe AS unsubscribe1, u1_.id AS id2, u1_.linkedin_id AS linkedin_id3, u1_.facebook_id AS facebook_id4, u1_.linkedin_profile AS linkedin_profile5, u1_.profile AS profile6, 
    CASE WHEN u1_.linkedin_id <> ''
    OR u1_.facebook_id <> ''
    THEN 1 
    ELSE 0 
    END AS sclr7, 
    CASE WHEN e0_.edition =23932
    THEN 'current'
    ELSE 'past'
    END AS sclr8
    FROM event_visitor e0_, user u1_
    WHERE e0_.user = u1_.id
    AND e0_.event =25162
    AND e0_.published =1
    AND e0_.showme =1
    GROUP BY e0_.user
    ORDER BY sclr7 DESC , e0_.id DESC , LENGTH( u1_.unsubscribe ) 
    LIMIT 30

在谷歌搜索了很多之后

• 按类型转换的订单（以有符号整数表示）ASC

• 按强制转换排序（u1_1.unsubscribe为有符号整数）ASC、sclr7说明、e0_1.id说明
  • 但是问题o/p-5，1，1，…等等

我提出的解决方案是：

• 按符号排序（强制转换（u1_1.unsubscribe AS SIGNED INTEGER））ASC、ABS（强制转换（u1_1.unsubscribe AS SIGNED INTEGER））、sclr7描述、e0_1.id描述

我需要实施abs功能原则

dql代码

     $from = 'Entities\EventVisitor visitor,Entities\User user';
   $qb = $this->em->createQueryBuilder();

  $qb->select("visitor.metadata,ABS( u1_.unsubscribe )as unsubscribe)
 ->add('from',$from)

 ->where('visitor.user=user.id')
 ->groupBy('visitor.user')
->orderBy('unsubscribe','asc')

error 500 internal error.

按ABS订购（取消订阅）吗，取消订阅不是一个选项-？你能帮我在条令中实现ABS功能吗
     $from = 'Entities\EventVisitor visitor,Entities\User user';
   $qb = $this->em->createQueryBuilder();

  $qb->select("visitor.metadata,ABS( u1_.unsubscribe )as unsubscribe)
 ->add('from',$from)

 ->where('visitor.user=user.id')
 ->groupBy('visitor.user')
->orderBy('unsubscribe','asc')

error 500 internal error.
