在运维的过程中,有时候需要定时将SQL查询的数据html">结果集以html表格形式发送邮件,因此需要将SQL查询得到的结果集拼接成html代码。对于这种情形通常有二种方式来完成。一是直接使用cron job来定时轮询并借助os级别的邮件程序来完成。其查询结果集可以直接在SQL*Plus下通过设置html标签自动实现html表格形式。一种方式是在Oracle中使用scheduler job来定时轮询。这种方式需要我们手动拼接html代码。本文即是对第二种情形展开描述。

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.
