Item Description: Bridges the gap between Perl and MySQL date-time types

Review Synopsis:

Time::Piece::MySQL is a very useful module for MySQL users. It is simply an extension to Time::Piece that provides a handful of methods for converting back and forth between Time::Piece objects and the MySQL date/time types: date, time, datetime, and timestamp. (The year type is available from Time::Piece, so it doesn't need to be here.)

As an example, say i had a table of events that contained an id and a datetime field:

+---------+------------------+
| Field   | Type             |
+---------+------------------+
| id      | int(10) unsigned |
| date    | datetime         |
+---------+------------------+
and i wanted to add 50 days to to each date. The following snippet would do just that:
use strict; use warnings; use DBI; use Time::Seconds; use Time::Piece::MySQL; my $dbh = DBI->connect( ... ); my $sth = $dbh->prepare('update events set date = ? where id = ?'); my $dates = $dbh->selectall_arrayref( 'select id,date from events', {Slice => {}} ); for (@$dates) { my $date = localtime->from_mysql_datetime( $_->{date} ); $date += ONE_DAY * 50; $sth->execute( $date->mysql_datetime, $_->{id} ); }
A very trivial example, but i think it demonstrates how it can make someone's Perl/MySQL script easier to work with.
