I had the same error when I tried to migrate Drupal database to a new local apache server(I am using XAMPP on Windows machine). Actually I don't know the meaning of this error, but after trying steps below, I imported the database without errors. Hope this could help:

Changing php.ini at C:\xampp\php\php.ini

max_execution_time = 600
max_input_time = 600
memory_limit = 1024M
post_max_size = 1024M

Changing my.ini at C:\xampp\mysql\bin\my.ini

max_allowed_packet = 1024M

回答2:

1. Goto XAMPP control panel> 2.Stop Apache and MySql services>

2. Click on Config of Apache>select php.ini and change the followings:
   max_execution_time = 600
max_input_time = 600
memory_limit = 1024M
post_max_size = 1024M
   

3. Click on Config button of MySql and select my.ini and change:
   max_allowed_packet = 1024M

4. Again Start the services and try.. i hope it will worksssss.

I had the same problem when trying to import a Wordpess MySQL dump to a new server. In the end after an hour debugging I had to manually remove the following tables from the .sql file:

wp_cf7dbplugin_st wp_cf7dbplugin_submits

There were some really large values (possibly PDF files) stored in some of the fields which were causing a problem.

Imported fine after I removed the tables from the script.
