From the command line: mysql --max_allowed_packet=100M Or modify the filemy.iniormy.cnfand put this line under [mysqld] section in your file: max_allowed_packet=100M The size is up to you, the bigger it is, the bigger packet size is allowed. The largest possible packet that can ...

默认情况下,MySQL 的导入文件大小限制为 1GB。这是通过 max_allowed_packet 参数来控制的。这个参数定义了 MySQL服务器和客户端之间传输数据的最大大小。如果超过了这个大小,MySQL 将会发送一个错误消息并停止导入。 如果你需要导入一个大于 1GB 大小的文件,你需要修改 max_allowed_packet 参数的值。你可以通过在 My...
--max_allowed_packet=<size> The maximum packet length to send to or receive from the server. (Default value is 16MB.) So as a client, it is apparently possible to pick your own setting for the maximum allowed packet size you will send or accept from the server. Indeed, I can actu...
. packet number(1字节), 从0开始的递增的 ● sql “select1” 的网络协议是? 协议头 ● packet length三个字节意味着MySQL packet最大16M大于16M则被分包(net_write_command, my_net_write) ● packet number分包从0开始,依次递增.每一次执行sql, packet_number清零(sql/net_serv.c:net_clear) ...
max_allowed_packet的协议限制为1GB。该值应为1024的倍数;非倍数的值向下舍入为最接近的倍数。 When you change the message buffer size by changing the value of the max_allowed_packet variable, you should also change the buffer size on the client side if your client program permits it. The ...
单张表size 过大,导致导入失败 解决: mysql 命令行模式下 set global max_allowed_packet = 1024*1024*160; 设置单张表的大小为 160 M; 详解: mysql 命令行模式下: show VARIABLES like '%max_allowed_packet%'; 捕获.PNG max_allowed_packet : 单张表的最大允许大小为 4 M;slave_max_allowed_packet:最...
max_allowed_packet 值设置过小将导致单个记录超过限制后写入数据库失败,且后续记录写入也将失败,为了数据完整性,需要考虑到事务因素。max_allowed_packet设置过大可能会导致服务器太忙来不及接收,网络差的时候也可能会出现丢包的现象。 注:如果是5.5以上版本,还需要设置max_long_data_size这个参数,一般和max_allowed...
The maximum size of one packet or any generated/intermediate string, or any parameter sent by the mysql_stmt_send_long_data() C API function. The default is 64MB The packet message buffer is initialized to net_buffer_length bytes, but can grow up to max_allowed_packet bytes when needed....
