1、准备导入数据
[root@D2-LZY245 ~]# cat /tmp/emp.txt
100,Steven,King,24000.00
101,Neena,Kochhar,17000.00
102,Lex,De Haan,17000.00
103,Alexander,Hunold,9000.00
104,Bruce,Ernst,6000.00
105,David,Austin,4800.00
106,Valli,Pataballa,4800.00
107,Diana,Lorentz,4200.00
108,Nancy,Greenberg,12008.00
109,Daniel,Faviet,9000.00
110,John,Chen,8200.00

2、创建InnoDB引擎表
mysql> create database test1;
Query OK, 1 row affected (0.00 sec)

mysql> use test1;
Database changed

mysql> create table emp(
-> employee_id int(10),
-> first_name varchar(50),
-> last_name varchar(50),
-> salary decimal(10,2)) engine=innodb charset=utf8;
Query OK, 0 rows affected (0.00 sec)

3、导入数据
[root@D2-LZY245 ~]# mysqlimport -uroot -p'123456' test1 --default-character-set=utf8 --fields-terminated-by=',' /tmp/emp.txt
mysqlimport: [Warning] Using a password on the command line interface can be insecure.
test1.emp: Records: 11 Deleted: 0 Skipped: 0 Warnings: 0

4、查看结果
mysql> select * from emp;
+-------------+------------+-----------+----------+
| employee_id | first_name | last_name | salary |
+-------------+------------+-----------+----------+
| 100 | Steven | King | 24000.00 |
| 101 | Neena | Kochhar | 17000.00 |
| 102 | Lex | De Haan | 17000.00 |
| 103 | Alexander | Hunold | 9000.00 |
| 104 | Bruce | Ernst | 6000.00 |
| 105 | David | Austin | 4800.00 |
| 106 | Valli | Pataballa | 4800.00 |
| 107 | Diana | Lorentz | 4200.00 |
| 108 | Nancy | Greenberg | 12008.00 |
| 109 | Daniel | Faviet | 9000.00 |
| 110 | John | Chen | 8200.00 |
+-------------+------------+-----------+----------+
11 rows in set (0.00 sec)
