I use DBI. And I want to make some like

INSERT INTO ... VALUES (the_generated_timestamp, ...);

What is the command? How could it be created, the perl ``ocaltimescalar value has a very complex, for human eyes optimized format (f.e.Mon Apr 28 15:58:51 2014). My goal were some like as the unixgettimeofday()` does (giving back the seconds since 1970.1.1), converted by some format string, which I can let eat by the Oracle.

But any simpler solution were also okay, if it exists.

It need to be generated in perl. INSERT ... (current_timestamp, ...) isn't okay.

Are you maybe looking for current_timestamp? INSERT INTO ... VALUES (current_timestamp, ...); – a_horse_with_no_name Apr 28 '14 at 14:16
@a_horse_with_no_name Thank you, but I need to generate it in Perl. – peterh Apr 28 '14 at 14:16
The generate the date as a string in e.g. ISO format, and use to_date() or to_timestamp() – a_horse_with_no_name Apr 28 '14 at 14:17
You can use TO_TIMESTAMP or to_timestamp_tz Oracle functions that convert string to timestamp . INSERT ... VALUES(TO_TIMESTAMP('string', 'format'), .... – a1ex07 Apr 28 '14 at 15:34

Something like this will do:

my ($second, $minute, $hour, $day, $month, $year, $weekday, $dayofyear, $dst) = localtime();

my $oracledatestring = sprintf "TO_DATE('%04d/%02d/%02d %02d:%02d:%02d', 'yyyymmdd HH24:MI:SS')", $year+1900, $month+1, $day, $hour, $minute, $second;

.. giving something like:

TO_DATE('2014/04/28 16:34:34', 'yyyymmdd HH24:MI:SS')

... which can then be inserted directly into an Oracle DATE column.

All a bit of a long way round, to be honest. Use SYSDATE in your INSERT statements instead.
