Question

我正在尝试使用ST_Intersection函数按城市Polyogn相交一个点，但是我没有运气（Hasura + Postgresql）

create table "public"."cities"(
  geom geometry(MultiPolygon, 4326) 
  //other colmuns
);

然后我在城市的多边形中添加了一行：

INSERT INTO "public"."cities"
VALUES(ST_GeomFromText('MULTIPOLYGON(((
5.334 36.213,5.335 36.22,5.356 36.225,5.365 36.233,5.371 36.232,5.378 36.237,5.387 36.24,5.39 36.243,5.395 36.244,5.398 36.248,5.406 36.249,5.413 36.253,5.421 36.25,5.431 36.249,5.435 36.246,5.433 36.24,5.434 36.239,5.433 36.231,5.44 36.232,5.445 36.23,5.447 36.227,5.453 36.227,5.457 36.229,5.462 36.227,5.477 36.231,5.482 36.238,5.49 36.238,5.491 36.24,5.495 36.241,5.503 36.241,5.506 36.237,5.506 36.234,5.509 36.231,5.51 36.225,5.509 36.216,5.502 36.211,5.502 36.207,5.498 36.202,5.498 36.199,5.502 36.194,5.502 36.183,5.499 36.18,5.499 36.177,5.497 36.175,5.492 36.174,5.487 36.169,5.481 36.17,5.481 36.163,5.478 36.159,5.475 36.158,5.476 36.154,5.472 36.148,5.472 36.145,5.469 36.142,5.452 36.141,5.44 36.133,5.438 36.13,5.433 36.13,5.43 36.138,5.42 36.137,5.418 36.139,5.41 36.136,5.406 36.136,5.402 36.139,5.392 36.137,5.384 36.138,5.369 36.13,5.364 36.132,5.364 36.135,5.346 36.138,5.345 36.143,5.35 36.151,5.347 36.156,5.347 36.164,5.343 36.171,5.343 36.175,5.338 36.18,5.336 36.187,5.333 36.191,5.334 36.194,5.333 36.201,5.336 36.205,5.334 36.213
)))', 4326) );

但是当我以Point为城市中心运行此查询时，我不返回任何数据。

select * 
from "public"."cities"
where ST_Intersects("public"."cities"."geom", ST_GeometryFromText('POINT(36.1917 5.4235)', 4326));

更新： 我将多边形存储在long-lat中，但是我用lat-long Point查询，这是我的错误

Postgis-检查点是否在多边形内
