<p class=MsoNormal>Check the DateTime::Format::Oracle documentation
for the NLS environment variables (<a
href="http://search.cpan.org/~kolibrie/DateTime-Format-Oracle-0.05/lib/DateTime/Format/Oracle.pm">http://search.cpan.org/~kolibrie/DateTime-Format-Oracle-0.05/lib/DateTime/Format/Oracle.pm</a>).
They control the DateTime's string format for the format and parse.
You will also need to set the Oracle session to match NLS or the to_date
it calls behind the scenes will break.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>The disagreement between NLS ENV and Session formats is
probably the cause of the DateTime->now not working and also the culprit for
truncating your \'SYSDATE' from before.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>We use these options:<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<div>
<p class=MsoNormal>$ENV{'NLS_DATE_FORMAT'} = 'YYYY-MM-DD';<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>$ENV{'NLS_TIMESTAMP_FORMAT'} = 'YYYY-MM-DD HH24:MI:SS';<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>...then we use this connect option to make the Oracle ones
match<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<div>
<p class=MsoNormal>on_connect_do => [<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> 'ALTER SESSION SET NLS_DATE_FORMAT =
\'YYYY-MM-DD\'',<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal> 'ALTER SESSION SET NLS_TIMESTAMP_FORMAT =
\'YYYY-MM-DD HH24:MI:SS\''<o:p></o:p></p>

<div>
<p class=MsoNormal><o:p> </o:p></p>
</div>
<div>
<p class=MsoNormal>This will give you Oracle DATE and DATETIME columns with
date precision and Oracle TIMESTAMP columns with time precision. If you
don't need the distinction, setting NLS_DATE_FORMAT to time precision
should fix the DateTime->now and the SYSDATE truncation.<o:p></o:p></p>

<p class=MsoNormal>I do most of my development against Oracle, although I try
to make my code DB generic where possible. If you use a DateTime object rather
than sysdate, DBIC will deflate it for you. Of course, creating the new object
is slower than simply using sysdate, so I guess it depends how speed sensitive
your app is...<o:p></o:p></p>
