建表 

CREATE TABLE `z_gis` (
  `id` varchar(45) NOT NULL,
  `name` varchar(10) NOT NULL COMMENT '姓名',
  `gis` geometry NOT NULL COMMENT '空间位置信息',
  `geohash` varchar(20) GENERATED ALWAYS AS (st_geohash(`gis`,8)) VIRTUAL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `id` (`id`),
  SPATIAL KEY `idx_gis` (`gis`),
  KEY `idx_geohash` (`geohash`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='空间位置信息

插入数据

insert into z_gis(id,name,gis) values
(replace(uuid(),'-',''),'张三',geomfromtext('point(108.9498710632 34.2588125935)')),
(replace(uuid(),'-',''),'李四',geomfromtext('point(108.9465236664 34.2598766768)')),

查询

. 查询张三的经纬度信息：astext()函数是将geometry类型转化为字符串

select name, astext(gis) gis from z_gis where name = '张三';
