* MySQL driver in transactional mode
|
|
*
|
|
* @deprecated
|
|
*
|
|
* This driver only supports the original MySQL driver in transactional mode. It
|
|
* is deprecated in PHP version 5.5 and removed in PHP version 7. It is deprecated
|
|
* as of ADOdb version 5.20.0. Use the mysqli driver instead, which supports both
|
|
* transactional and non-transactional updates
|
|
*
|
|
* This file is part of ADOdb, a Database Abstraction Layer library for PHP.
