Import a large sql dump file

1) Set network buffer length to a large byte number. The default value may throw errors for such large data files

set global net_buffer_length=1000000;

2) Set maximum allowed packet size to a large byte number.The default value may throw errors for such large data files.

set global max_allowed_packet=1000000000;

3) Disable foreign key checking to avoid delays,errors and unwanted behaviour

SET AUTOCOMMIT = 0;
SET UNIQUE_CHECKS = 0;
SET foreign_key_checks = 0;
