  日常任务是:

  1)定期完成数据库的完全备份或差异备份。

  2)定期清理备份文件,因为存储空间有限,可能只需要保存一个时期段内的文件(比如一周内或一月内)。

  而如何做到这两点呢?笔者相信在SQL SERVER2005版本出来之前要实现这种功能,也是可以实现的,只是实现定期清理备份文件显得不那么直接,一般需要手写批处理作业维护,,而在SQL Server 2005版本中,这些功能已经被设计成为预制的组件,只需要在数据维护计划中进行拖拽并设置相关属性就可以了,相关步骤如下:

  第一步:新建维护计划

  在服务器 管理维护计划鼠标右键点击新建维护计划。

  第二步:设计维护计划

  2.1 拖拽 维护计划中的任务工具箱 的“备份数据库任务”到维护计划设计器。

  2.2 拖拽 维护计划中的任务工具箱 的“清除历史记录任务”到维护计划设计器。

  2.3拖拽 维护计划中的任务工具箱 的“清除维护任务”到维护计划设计器。

  如下图所示:

  图6

  本步骤完成了作业属性的设置。系统将按照设置定期运行维护作业。

  第三步:保存维护计划

  到此,只需要查看日志记录,就可以跟踪本计划的完成情况,根据成功记录与否可以调整和修改本维护计划。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
