import mysql from file code example

Example 1: import mysql command line without database

mysql -u username -p database_name < file.sql

Note-1: It is better to use the full path of the SQL file file.sql.
Note-2: Use -R and --triggers to keep the routines and triggers of original database.
		They are not copied by default.
Note-3 You may have to create the (empty) database from mysql if it 
		doesn't exist already and the exported SQL don't 
        contain CREATE DATABASE (exported with --no-create-db or -n option), 
        before you can import it.
