先创建几个函数
CREATE EXTENSION cube;
CREATE EXTENSION earthdistance;
查询规定范围内
SELECT
A . ID,
A ."name"
FROM
t_base_customer A
WHERE
earth_box (
ll_to_earth (36.702286, 119.195057),
300.0
) @> ll_to_earth (A .latitude, A .longitude);
按距离排序
SELECT
A . ID,
A ."name",
earth_distance (
ll_to_earth (36.702286, 119.195057),
ll_to_earth (A .latitude, A .longitude)
) AS distance
FROM
t_base_customer A
ORDER BY
distance ASC;
