MYSQL Big Data Import

Thanks for the Code provided by XP!
Record it here, because it will be used later. It will be used for data query!
Step 1: mysql-h localhost-uroot
Step 2: show databases;
Step 3: use changchunmap;
Step 4: show tables;
Step 5: load data local infile "d:/c.txt" replace into table changchunmap fields terminated '';
No;
Load data local infile "d:/migration/mysql/babel_topic.txt" replace into table babel_topic_test fields terminated''
Load data local infile "d:/migration/mysql/babel_user.txt" replace into table babel_user_test fields terminated by '\ t'
During the import process, the length of some tables can be changed to NULL because the data of some fields is NULL. To correctly import the data, make sure that the following fields are modified:
Babel_topic: tpc_uname VARCHAR (192) can be NULL
Babel_user: usr_password VARCHAR (64) can be NULL
Usr_nick VARCHAR (192) can be NULL
Load data local infile "d:/c.txt" replace into table changchunmap fields terminated''
