Mysql查询

select * 
from test 
where name like 'na%' or 
      name like '% na%' or 
      name like '%na%';

按顺序返回 1然后2 但我想按顺序2和1.那就是要给'％na％'然后'％na％'更多的权重

这有什么办法可以在mysql中完成吗？

Answer 1

select * from 
(
select * from name where name like '% na%'
union
select * from name where name like 'na%'
union
select * from name where name like '%na%'
) a

Answer 2

您应该在您的选择和订单中创建虚拟字段。例如：

select test.*,
case when name like '% na%'
         then 1
     else 2
end as OrderField
from test 
where name like 'na%' or 
      name like '% na%' or 
      name like '%na%'
order by OrderField

mysql搜索权重结果
