经过几天的寻找，并尝试了我找到的所有内容后，我来这里询问如何使用 PostGis 计算 Postgres 上两点之间的距离。我有一张名为“位置”的表。该表有一个点类型的“坐标”列。当用户在应用程序上插入值时，我需要获取按近距离排序的位置。我知道我需要使用 ST_Distance，但每次我尝试投射坐标点时我都不能。我需要以公里为单位的结果。

我尝试：

SELECT ST_Distance('POINT(0.0 0.0)', ST_GeomFromText(location.coordenate)) FROM app.location as location;

当我发现此错误时，我只是尝试创建一个新服务。当我尝试列出可用的学说命令时，它显示下一个错误：

Doctrine\\ORM\\Mapping\\OneToMany::__construct() 必须是数组类型或 null，给定字符串，在 /var/www/html/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/ 中调用文档解析器.php

我尝试重置负责它的实体，但没有结果。这是所有跟踪：
