百度地图api - mysql PHP 如何实现空间距离的检索 计算配送范围
我觉得这似乎是一个新的领域，用sql查询能计算空间坐标，返回指定范围内的点吗？类似，美团，饿了么那样的，根据餐厅的配送范围检索可以配送的餐厅；
正是因为地图API解决不了我的问题：

https://segmentfault.com/q/1010000004586...
所以我就想自己解决这个问题了，需要有专门的服务软件吗？mysql 有个geometry类型字段可以用吗？
写sql查询应该会很有性能问题吧，感觉怪怪的。
求有经验的大神提供思路，谢谢！

这些数据都是用离线脚本跑的，不是实时计算的
都有专门的检索组在做，和搜索一样。不是php搞得。
大神在哪里啊？
我们的项目里不得不把数据迁移到MongoDB一份
原因是MongoDB 地里位置好用。
我们的Mysql用的阿里云RDS还在5.6
