将int转换为timestamp或任何日期格式的sql

Question

I am pulling from a db and have a row that has a timestamp and I want it to show up as a date in my python script. Here is an example of the data

1422471599
1422471599
1422471599

Here is what I am trying to do in sql

convert(timestamp, cast(time as varchar(12)))

I would also be willing to try and convert this in python

Answer 1

You could use datetime.fromtimestamp :

from datetime import date

s = 1422471599

print(date.fromtimestamp(s)
2015-01-28

Answer 2

select timestamp 'epoch' + your_column *  interval '1 second' from your_table;
