mysql中计算经纬度方法
select * ,3956*2*asin(sqrt(power(sin((122.4058-abs(dest.lat))*pi()/180/2),2)+cos(122.4058/180)*cos(abs(dest.lat)*pi()/180)*power(sin((37.7907-dest.lon)*pi()/180/2),2))) as distance from sp_zxcplace dest HAVING distance<10000 order by distance
Mysql根据经纬度算距离返回米
亲测ok
SELECT pId,name,lon,lat, ROUND(6378.138*2*ASIN(SQRT(POW(SIN((34.3574030000*PI()/180-lat*PI()/180)/2),2)+COS(34.3574030000*PI()/180)*COS(lat*PI()/180)*POW(SIN((108.9263460000*PI()/180-lon*PI()/180)/2),2)))*1000) AS distance FROM sp_zxcplace HAVING distance<10000 ORDER BY distance
