表company
id city top
1 北京,上海 北京
2 济南,石家庄 济南
3 北京 北京

排序规则:
1、搜索“北京”列出`city`中有“北京”的;
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 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 

这个好像不是我想要的

试试这个,测试可以

SELECT *FROM testWHERE city LIKE '%北京%'ORDER BY (top LIKE '%北京%') DESC , id DESC

表名没改,test改成company

试试这个,测试可以
