mysql经纬度计算距离，官方支持方法

先看下官方文档

ST_Distance_Sphere(g1, g2 [, radius])

Returns the mimimum spherical distance between two points and/or multipoints on a sphere, in meters, or NULL if any geometry argument is NULL or empty.

Calculations use a spherical earth and a configurable radius. The optional radius argument should be given in meters. If omitted, the default radius is 6,370,986 meters. An ER_WRONG_ARGUMENTS error occurs if the radius argument is present but not positive.

The geometry arguments should consist of points that specify (longitude, latitude) coordinate values:

Supported argument combinations are (Point, Point), (Point, MultiPoint), and (MultiPoint, Point). An ER_GIS_UNSUPPORTED_ARGUMENT error occurs for other combinations.

If any geometry argument is not a syntactically well-formed geometry byte string, an ER_GIS_INVALID_DATA error occurs.
```
mysql> SET @pt1 = ST_GeomFromText('POINT(0 0)');
mysql> SET @pt2 = ST_GeomFromText('POINT(180 0)');
mysql> SELECT ST_Distance_Sphere(@pt1, @pt2);
+--------------------------------+
| ST_Distance_Sphere(@pt1, @pt2) |

```
- Longitude and latitude are the first and second coordinates of the point, respectively.
- Both coordinates are in degrees.
- Longitude values must be in the range (-180, 180]. Positive values are east of the prime meridian.
- Latitude values must be in the range [-90, 90]. Positive values are north of the equator.

此方法时mysql官方支持函数

select
ST_Distance_Sphere(point (目标纬度, 目标经度),point(纬度,经度)) distance
from table 
举个例子

select  ST_Distance_Sphere(point (113.6350421, 34.7950488),point(113.6051975,34.7418565)) AS distance from demo_table
