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 The following options may be given as the first argument: --print-defaults Print the program argument list and exit. --no-defaults Don't read default options from any option file, except for login file. --defaults-file=# Only read default options from the given file #. --defaults-extra-file=# Read this file after the global files are read. --defaults-group-suffix=# Also read groups with concat(group, suffix) --login-path=# Read this path from the login file. --bind-address=name IP address to bind to. --character-sets-dir=name Directory for character set files. --default-character-set=name Set the default character set. -c, --columns=name Use only these columns to import the data to. Give the column names in a comma separated list. This is same as giving columns to LOAD DATA INFILE. -C, --compress Use compression in server/client protocol. -#, --debug[=#] This is a non-debug version. Catch this and exit. --debug-check This is a non-debug version. Catch this and exit. --debug-info This is a non-debug version. Catch this and exit. --default-auth=name Default authentication client-side plugin to use. -d, --delete First delete all rows from table. --enable-cleartext-plugin Enable/disable the clear text authentication plugin. --fields-terminated-by=name Fields in the input file are terminated by the given string. --fields-enclosed-by=name Fields in the import file are enclosed by the given character. --fields-optionally-enclosed-by=name Fields in the input file are optionally enclosed by the given character. --fields-escaped-by=name Fields in the input file are escaped by the given character. -f, --force Continue even if we get an SQL error. -?, --help Displays this help and exits. -h, --host=name Connect to host. -i, --ignore If duplicate unique key was found, keep old row. --ignore-lines=# Ignore first n lines of data infile. --lines-terminated-by=name Lines in the input file are terminated by the given string. -L, --local Read all files through the client. -l, --lock-tables Lock all tables for write (this disables threads). --low-priority Use LOW_PRIORITY when updating the table. -p, --password[=name] Password to use when connecting to server. If password is not given it's asked from the tty. --plugin-dir=name Directory for client-side plugins. -P, --port=# Port number to use for connection or 0 for default to, in order of preference, my.cnf, $MYSQL_TCP_PORT, /etc/services, built-in default (3306). --protocol=name The protocol to use for connection (tcp, socket, pipe, memory). -r, --replace If duplicate unique key was found, replace old row. --secure-auth Refuse client connecting to server if it uses old (pre-4.1.1) protocol. Deprecated. Always TRUE -s, --silent Be more silent. -S, --socket=name The socket file to use for connection. --ssl-mode=name SSL connection mode. --ssl Deprecated. Use --ssl-mode instead. (Defaults to on; use --skip-ssl to disable.) --ssl-verify-server-cert Deprecated. Use --ssl-mode=VERIFY_IDENTITY instead. --ssl-ca=name CA file in PEM format. --ssl-capath=name CA directory. --ssl-cert=name X509 cert in PEM format. --ssl-cipher=name SSL cipher to use. --ssl-key=name X509 key in PEM format. --ssl-crl=name Certificate revocation list. --ssl-crlpath=name Certificate revocation list path. --tls-version=name TLS version to use, permitted values are: TLSv1, TLSv1.1 --use-threads=# Load files in parallel. The argument is the number of threads to use for loading data. -u, --user=name User for login if not current user. -v, --verbose Print info about the various stages. -V, --version Output version information and exit.
