How do I convert character varying to timestamp in postgresql which is in the format [ “2020-09-21T13:56:58Z” ]

Question

I tried doing this but got an error as:

ERROR: column "2020-09-21t13:56:58z" does not exits

Select to_timestamp("2020-09-21T13:56:58Z", "YYYY-MM-DDTHH24:MI:SSZ");

Answer 1

Try to_char() instead. As follows -

Sample data

create table a (
  date_time timestamp
  );
  
insert into a (date_time) values ('2020-09-21T13:56:58Z')

SELECT

select to_char(date_time, 'YYYY-MM-DDTHHH24:MI:SSZ') as time
from a

Result:

time
2020-09-21ST13:56:58Z
