sqlite3时间戳列

Question

I feel stupid, but I can't get a TIMESTAMP column to be shown in human understandable way in a SELECT.

I could do that in MySQL, not in sqlite3.

Could someone show me an example please?

Thanks

Answer 1

Here is an example:

SELECT strftime('%Y', datetime(birthday_field, 'unixepoch', 'localtime'))
AS birthday_year 
FROM birthdays;

The following is a complete list of valid strftime() substitutions:

%d      day of month: 00
%f      fractional seconds: SS.SSS
%H      hour: 00-24
%j      day of year: 001-366
%J      Julian day number
%m      month: 01-12
%M      minute: 00-59
%s      seconds since 1970-01-01
%S      seconds: 00-59
%w      day of week 0-6 with sunday==0
%W      week of year: 00-53
%Y      year: 0000-9999
%%      % 

Answer 2

SELECT datetime（timestamp，'unixepoch'，'localtime'）;
