我有一个2.5 GB的生产数据库，该数据库是使用glm导出的。
我尝试通过运行
mysqldump文件导入另一台服务器
mysql -uroot moodle
它会运行几秒钟并卡住。当我选中.dump
mysql_error.log在生产数据库中工作正常，会出现什么问题？
我在Windows Server 2012中使用2018-06-27 11:14:36 5000 [ERROR] Incorrect definition of table mysql.column_stats: expected column 'max_value' at position 4 to have type varbinary(255), found type varchar(255).
