| 目前还是beta版本哦，有兴趣的便宜可以下载测试 MySQL 5.4 Downloads ： http://dev.mysql.com/downloads/mysql/5.4.html As with any other pre-production set of software, the preview release of MySQL 5.4 is not recommended for use on production systems. When using MySQL 5.4, note that it is good practice to back up your data before installing the new software. MySQL/Sun generally recommends that you dump and reload your tables from any previous version to upgrade to MySQL 5.4.(责任编辑：admin) |
