V5.06 16 Oct 2008 (c) 2000-2008 John Lim. All rights reserved.
|
||||
Released under both BSD license and Lesser GPL library license.
|
||||
Whenever there is any discrepancy between the two licenses,
|
||||
the BSD license will take precedence.
|
||||
|
||||
Latest version is available at http://adodb.sourceforge.net
|
||||
|
||||
Portable version of oci8 driver, to make it more similar to other database drivers.
|
||||
The main differences are
|
||||
|
||||
1. that the OCI_ASSOC names are in lowercase instead of uppercase.
|
||||
2. bind variables are mapped using ? instead of :<bindvar>
|
||||
|
||||
Should some emulation of RecordCount() be implemented?
