MySQL之根据经纬度查询多少公里范围内的数据
MySQL之根据经纬度查询多少公里范围内的数据
- 根据经纬度查询多少公里范围内的数据
- 创建地址表，存储经纬度信息
- 插入数据
- 根据当前经纬度查询所有地址，按距离由近到远排序
- 查询结果（距离以km为单位）
根据经纬度查询多少公里范围内的数据
可根据实际业务逻辑去套用该方法
创建地址表，存储经纬度信息
//创建地址表，存储位置信息
CREATE TABLE `address` (
`longitude` varchar(255) DEFAULT NULL COMMENT '经度',
`latitude` varchar(255) DEFAULT NULL COMMENT '纬度'
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
