 MySQL 触发器功能比较简单,大部分只用来简单的更新第三方表,今天我来演示下MySQL触发器在造数据方面的功效。 

 

 

下面是基表结果:

 

 

 

这个是对基表的批量插入存储过程:

 

 

 

 

 

单线程造数据:

 

 

  •  

    1KW行记录花了8分钟多,也就是一个线程每秒插入2W条记录。

     

     

     

     

    创建复制表:

     

  •  

    这里比较恶心的是多建立了一个表tb3,因为MySQL触发器暂时不支持自己对自己插入。

     

     

     

    这个是基于表tb3的后置插入触发器:

     

     

     

    1KW记录花了不到6分钟,美国空间,也就是一个线程每秒插入大于3W记录。

     

  • Query OK, 1 row affected (5 min 14.07 sec) 
  •  

    可以看到,速度比存储过程提升了60%左右。 

     

    怎么样,很HAPPY吧?
