@version v5.20.9 21-Dec-2016
@copyright (c) 2000-2013 John Lim (jlim#natsoft.com). All rights reserved.
@copyright (c) 2014 Damien Regad, Mark Newnham and the ADOdb community
This is a version of the ADODB driver for DB2. It uses the 'ibm_db2' PECL extension
for PHP (http://pecl.php.net/package/ibm_db2), which in turn requires DB2 V8.2.2 or
higher.
Originally tested with PHP 5.1.1 and Apache 2.0.55 on Windows XP SP2.
More recently tested with PHP 5.1.2 and Apache 2.0.55 on Windows XP SP2.
This file was ported from "adodb-odbc.inc.php" by Larry Menard, "larry.menard#rogers.com".
I ripped out what I believed to be a lot of redundant or obsolete code, but there are
probably still some remnants of the ODBC support in this file; I'm relying on reviewers
of this code to point out any other things that can be removed.
