[TASK] Update ADOdb to 5.18
[Packages/TYPO3.CMS.git] / typo3 / sysext / adodb / adodb / drivers / adodb-oci8po.inc.php
1 <?php
2 /*
3 V5.18 3 Sep 2012 (c) 2000-2012 John Lim. All rights reserved.
4 Released under both BSD license and Lesser GPL library license.
5 Whenever there is any discrepancy between the two licenses,
6 the BSD license will take precedence.
7
8 Latest version is available at http://adodb.sourceforge.net
9
10 Portable version of oci8 driver, to make it more similar to other database drivers.
11 The main differences are
12
13 1. that the OCI_ASSOC names are in lowercase instead of uppercase.
14 2. bind variables are mapped using ? instead of :<bindvar>
15
16 Should some emulation of RecordCount() be implemented?
