如何选择表中除一个以外的所有列

问题描述

我的代码如下：

 CREATE TABLE tableC AS
 (SELECT tableA.*,
  ST_Intersection (B.geom, A.geom) as geom2  -- generate geom
 FROM tableB, tableA
 JOIN tableB
 ON ST_Intersects (A.geom, b.geom)
 WHERE test.id = 2);

现在正在工作，但是我有两列geom和geom2！
内部几何列中，我将基于交点获得新的几何形状。那么，如何选择除geom列之外的tableA？

Now It is working but I have two columns geom and geom2!Inside geom column I will have the new geometry based on the intersection. So how can I select tableA except the geom column?

推荐答案

创建具有所有列的表，然后删除 geom 列并重命名新的：

Create the table with all the columns and after that drop the geom column and rename the new one:

CREATE TABLE tableC AS
SELECT
    tableA.*,
    ST_Intersection (B.geom, A.geom) as geom2  -- generate geom
FROM
    tableA inner JOIN tableB ON ST_Intersects (A.geom, b.geom)
WHERE test.id = 2
;

alter table tableC drop column geom;
alter table tableC rename column geom2 to geom;
