创建geo表

create table geo(

    geo_id INT NOT NULL AUTO_INCREMENT,

    lng float NOT NULL,

    lat float NOT NULL,

    name VARCHAR(100) NULL,

    PRIMARY KEY ( geo_id )

);

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.302416,33.958887,"实验小学");

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.303997,33.95188,"宿迁市人民医院");

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.302991,33.935828,"宿迁学院");

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.28215,33.959307,"金陵名府");

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.290081,33.925404,"润园");

INSERT INTO `geo`(`lng`, `lat`, `name`) VALUES (118.354751,33.959007,"国际馆");

SELECT

  geo_id, `name`,(

    6371 * acos (

      cos ( radians(33.958887) )

      * cos( radians( lat ) )

      * cos( radians( lng ) - radians(118.302416) )

      + sin ( radians(33.958887) )

      * sin( radians( lat ) )

    )

  ) AS distance

FROM geo

HAVING distance < 20

ORDER BY distance

LIMIT 0 , 20；

　　其中33.958887是纬度，118.302416是经度，6371是地球的半径。
