mysqlimport 数据导入程序

mysqlimport 数据导入程序
mysqlimport客户端提供了一个命令行接口来执行load data infile SQL语句。大多数的mysqlimport直接与load data infile语法的子句相关。

其使用语法为:

shell>mysqlimport [options] db_name textfile1 [textfile2 ...]


mysql -e 'create table imptest(id int,n varchar(30))'  mysql


[mysql@localhost ~]$ mysql -uroot -pxxzx7817600 -e 'create table imptest(id int,n varchar(30))'  mysql
mysql: [Warning] Using a password on the command line interface can be insecure.

Loads tables from text files in various formats.  The base name of the
text file must be the name of the table that should be used.
If one uses sockets to connect to the MySQL server, the server will open and
read the text file directly. In other cases the client will open the text
file. The SQL command 'LOAD DATA INFILE' is used to import the rows.

Usage: mysqlimport [OPTIONS] database textfile...
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /mysqlsoft/mysql/etc/my.cnf /mysqlsoft/mysql/my.cnf ~/.my.cnf
The following groups are read: mysqlimport client
