2、`top`中有“北京的靠前”;
3、`id`从大到小排列

select * from company where city like '%北京%' and top like '北京' order by id desc union select * from company where city like '%北京%' and top not like '北京' order by id desc

SELECT *FROM testWHERE city LIKE '%北京%'ORDER BY (top LIKE '%北京%') DESC , id DESC
表名没改,test改成company
