PG COPY error: invalid input syntax for integer

Question

Running COPY results in ERROR: invalid input syntax for integer: \"\" error message for me. What am I missing?

My /tmp/people.cs

Answer 1

I think it's better to change your csv file like:

"age","first_name","last_name"
23,Ivan,Poupkine
,Eugene,Pirogov

It's also possible to define your table like

CREATE TABLE people (
  age        varchar(20),
  first_name varchar(20),
  last_name  varchar(20)
);

and after copy, you can convert empty strings:

select nullif(age, '')::int as age, first_name, last_name
from people
