公式如下,单位米:
第一点经纬度:lng1 lat1
第二点经纬度:lng2 lat2
round(6378.138*2*asin(sqrt(pow(sin( (lat1*pi()/180-lat2*pi()/180)/2),2) cos(lat1*pi()/180)*cos(lat2*pi()/180)* pow(sin( (lng1*pi()/180-lng2*pi()/180)/2),2)))*1000)
例如:
SELECT store_id,lng,lat, ROUND(6378.138*2*ASIN(SQRT(POW(SIN((22.299439*PI()/180-lat*PI()/180)/2),2) COS(22.299439*PI()/180)*COS(lat*PI()/180)*POW(SIN((114.173881*PI()/180-lng*PI()/180)/2),2)))*1000) AS juli FROM store_info ORDER BY juli DESC LIMIT 316
