将csv文件导入到mysql

 

首先，为自己要导入的文件按照属性创建好表：

mysql> create table xxx( 
-> id int not null primary key,
 -> name char(30) character set utf8 not null, 
-> level char(30) character set utf8 not null,
 -> profession char(30) character set utf8 not null, 
-> work_unit char(100) character set utf8 not null 
-> ); 
Query OK, 0 rows affected, 4 warnings (0.02 sec)

 

注意，当表中的数字过大时，最好将其数据类型设置为字符型。我这里开始时设置为INT,也就是4个字节，结果报错了。

所以我又将其修改了下：

mysql> alter table qulification modify id varchar(100);

 

导入CSV文件，我开始时将源文件保存在了普通文件夹里，结果报出安全错误：

mysql> load data infile \'/home/xxx/xxx/xxx.csv\' into table qulification fields terminated by \',\'; 

ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

 

 

解决办法1：

• 查找MYSQL指定的安全导入导出文件夹：

• mysql> show variables like "secure%"; 
  +------------------+-----------------------+ | 
     Variable_name | Value | 
  +------------------+-----------------------+ |
   secure_file_priv | /var/lib/mysql-files/ | 
  +------------------+-----------------------+

   

• 复制源文件到指定文件夹 

  sudo cp xxx/xxx/xxx.csv /var/lib/mysql-files/

   

• 将指定文件夹里的源文件导入MySQL：

• `mysql> load data infile \'/var/lib/mysql-files/xxx.csv\' into table qulification fields terminated by \',\'; 
  
  Query OK, 3083 rows affected (0.19 sec) Records: 3083 Deleted: 0 Skipped: 0 Warnings: 0

   

 

解决办法2：

参照官网对这个字段的解释：

secure_file_priv may be set as follows:

• If empty, the variable has no effect. This is not a secure setting.

• If set to the name of a directory, the server limits import and export operations to work only with files in that directory. The directory must exist; the server will not create it.

• If set to NULL, the server disables import and export operations.

可自行到Mysql的配置文件中修改相应字段。
