将列数据添加到基于与另一个表的几何交集的表中-PostgreSQL

Question

我的城市已经定义了一些Urban Revitalization Perimeters使用PostGIS，我将城市分开了Blocks within Perimeters和Buildings within Perimeters。我现在想做的是用两个新列更新buildings表，将它们与它们所在的块相关联。

以下是Blocks表的示例，两列qd_setor和qd_fiscal是我需要传递给Buildings表的信息

 qd_setor | qd_fiscal |  wkb_geometry 
----------+-----------+---------------
 041      | 038       | 010600...
 086      | 302       | 010600...
 041      | 076       | 010600...
 075      | 054       | 010600...
 019      | 055       | 010600...

这是“建筑物”表的示例：

  ed_id  | ed_area | ed_altura |  ed_distrito  | wkb_geometry
---------+---------+-----------+---------------+--------------
 2739627 | 187.211 |     6.922 | SANTA_CECILIA | 010600...
 2739628 |  240.39 |    43.382 | SANTA_CECILIA | 010600...
 2739781 |  51.758 |     4.668 | SANTA_CECILIA | 010600...
 2739629 | 388.264 |    52.907 | SANTA_CECILIA | 010600...

这是我用来创建块和建筑物表的查询：

CREATE TABLE quadras_opurb AS
SELECT q.qd_setor, q.qd_fiscal, q.wkb_geometry
FROM quadra_fiscal q
WHERE EXISTS (
SELECT ou_nome
FROM op_urbana_valid o
WHERE
ST_Intersects(q.wkb_geometry, o.wkb_geometry)
);

这是预期的结果，所以一旦完成，我不必测试所需的块与建筑物之间的交集，我只需按qd_setor和qd_fiscal进行过滤：

  ed_id  | ed_area | ed_altura |  ed_distrito  | wkb_geometry | qd_setor | qd_fiscal 
---------+---------+-----------+---------------+--------------+----------+------------
 2739627 | 187.211 |     6.922 | SANTA_CECILIA | 010600...    | 041      | 038       
 2739628 |  240.39 |    43.382 | SANTA_CECILIA | 010600...    | 041      | 038       
 2739781 |  51.758 |     4.668 | SANTA_CECILIA | 010600...    | 041      | 038       
 2739629 | 388.264 |    52.907 | SANTA_CECILIA | 010600...    | 086      | 302
 2739631 | 187.244 |    22.865 | SANTA_CECILIA | 010600...    | 086      | 302  

请注意，由于一个块中包含多个建筑物，因此qd_setor和qd_fiscal将重复几次。

感谢您的帮助！

所以我想通了，我使用以下查询：

CREATE TABLE ed_quadra AS
SELECT
q.qd_setor AS setor,
q.qd_fiscal AS quadra,
e.*
FROM ed_opurb AS e
JOIN quadras_opurb AS q
ON ST_Intersects(e.wkb_geometry, q.wkb_geometry)
ORDER BY q.qd_setor ASC, q.qd_fiscal ASC;
