mysql gis基本使用

  # 插入空间数据

  INSERT INTO `t_pot` VALUES ('1', '北京', POINT(116.401394,39.916042));

  INSERT INTO `t_pot` VALUES ('2', '广州', ST_GEOMFROMTEXT('POINT(113.295701 23.008163)'));

  #查询

  SELECT pot FROM t_pot SELECT ST_ASTEXT(pot) FROM t_pot

  # ST_Distance_Sphere 两点的直线距离:米

  SELECT ST_Distance_Sphere(POINT(113.950339,22.54387),POINT(113.295701,23.008163))

  # st_distance返回的距离不是米

  SELECT st_distance (POINT (1, 1),POINT(2,2) ) * 111195

  # 添加空间索引

  ALTER TABLE t_pot ADD SPATIAL INDEX(pot);

  # 文本转化为空间数据

  SELECT ST_GEOMFROMTEXT("POINT(1 2)")

  # 空间数据字符串化

  SELECT ST_ASTEXT(POINT(1,2)) SELECT ST_ASTEXT(ST_GEOMFROMTEXT("POINT(1 2)"))

  # 经纬度转geoHash

  SELECT st_geohash(POINT(113.295701,23.008163),8)
