Insert 1 milion record

Well if ID is primary key then it should be auto-incremented as you set it, so it is taken care off already.  Your example is like
ID isnt.  I would have it as primary key then problem is solved

Ok for insert ID,my problem solved.
Now how do i insert many record?(about 1 million)

you can do from code level but it is not recommended.  I found it is easier just use this

https://dev.mysql.com/doc/refman/5.7/en/load-data.html

ie. using command from mysql > LOAD DATA INFILE 'users.txt' INTO TABLE yourdb.users;

/* Assume you have db name as yourdb and table users, your users.txt should be comma seperated */

Try a simple test file with few names to see how it goes then you can go from there.

Hey i cannot access to command line mysql
How do it?

The best way is using MySQL Tools like MySQL Workbench, Navicat, SQLyog to do the Import / Export.
