DBD::Oracle 1.21 Released
Apr 18, 2008 / By John Scoles
The latest release of DBD::Oracle is now ready and can be found at: CPAN DBD::Oracle. It is a Perl module that works with the DBI module to provide access to Oracle databases. It is maintained by me, John Scoles, under the auspices of The Pythian Group as open source/free software.
The release has been fully tested with the latest version of DBI (1.601).
Below is the list of the changes and/or fixes in this release.

In this release there are a number of new features. One important one you might want to have a look at is support for binding an array for in-out operations with
execute_array. Given this SQL:
INSERT INTO foo (id, bar) VALUES (foo_id_seq.nextval, ?) RETURNING id INTO ?
execute_array to insert 200 records, you will get an array back of the 200 new IDs inserted.
I have also added support for directly inserting of large XML files into an XMLType field.
Another important addition is support for Persistent LOBs if you are using Oracle 10.2 or later. You can now treat LOBs as if they were any other form of data, so say goodbye to LOB locators.
Finally, I have added support for native Oracle ‘Scrolling Cursors’.
There were also a number of bug fixes and code updates as listed above.
Cheers, John Scoles.
