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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
