推荐答案

这可能是因为 max_allowed_packet

This may be because of max_allowed_packet

my.ini/my.cnf 文件中的更改.在文件中包含 [mysqld] 下的单行

Change in the my.ini/my.cnf file. Include the single line under [mysqld] in your file

max_allowed_packet=500M

现在完成后重新启动 MySQL 服务.您可以像这样在 mysql 中看到它的当前值:

now restart the MySQL service once you are done. You can see it's curent value in mysql like this:

SHOW VARIABLES LIKE 'max_allowed_packet'
