Packet for query is too large

Encountered database error: Error occurred while processing the request. Error from database server or driver.Packet for query is too large (3742402 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.. Details:

解决：

MySQL的一个系统参数：max_allowed_packet，其默认值为1048576(1M)，

可以先查询一下：show VARIABLES like '%max_allowed_packet%';

修改此变量的值：MySQL安装目录下的my.ini文件中的[mysqld]段中的＂max_allowed_packet = 1M＂，如更改为4M(如果没有这行内容，增加一行)，保存，重新启动MySQL服务。现在可以load大于1M的文件了。
