PostgreSQL ORDER BY列位置（而不是列名）

Question

Basically, I don't want:

SELECT firstname, lastname FROM person ORDER BY lastname;

But rather:

SELECT firstname, lastname FROM person ORDER BY <column number 2>;

I could create a mapping but I was wondering if there is a native trick to do it.

Answer 1

SELECT firstname, lastname 
FROM person 
ORDER BY 2;  --2nd column
