使用案例
SQL防注入
我们通过sql格式化以后，可有效防注入。
以%作为标识，%后面的字符为格式化参数的数据类型。支持的类型有：
- %t：表名(Table)，将被进行数据表名称反注入处理；
- %c：字段名(Column)，将被进行数据表字段名反注入处理；
- %n：数字值(Number)，将被过滤掉非数字和.的字符；
- %i：整形(Int)，将被强制转换为整形；
- %f：浮点型(Float)，将被强制转换为浮点型；
- %s：字符串值(String)，将被进行字符串值反注入处理;
- %x：保留不处理
例如：
使用事务
使用事务的前提是：你使用的引擎必须支持事务。MyISAM、MEMORY引擎不支持事务，InnoDB引擎支持事务。MySQL经过多年的发展，InnoDB引擎已经是MySQL引擎中最有优势的引擎，所以推荐你优先使用InnoDB引擎。
可以嵌套启用事务，最终只在最上一级事务提交后才会真正执行事务。
