Hi,
See
error-when-migrating-wordpress-database-to-new-serverA priori, this is not a MySQL error, but a WordPress configuration error.
You can try to increase the following values:
php_admin_value upload_max_filesize 128M
php_admin_value post_max_size 128M
in the file wamp(64)/alias/phpmyadmin.conf.
