I've tried to import a sql file (340Mb) with this statement:
mysql -u <user> -p --max_allowed_packet=1024M <database> < <file>.sql
And I get the error message after a while:
"ERROR 2006 (HY000) at line : MySQL server has gone away"
However if I use a MySQL manager like in this case Sequel Pro it works fine.
Can't understand why it doesn't work on the command line.
