求写一SQL语句
本帖最后由 xuz0917 于 2013-04-14 15:29:26 编辑 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
SQL mysql sql排序 php ------解决方案--------------------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
------解决方案--------------------<br />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 <br />
