MySQL Import and Export tool mysqldump command detailed

To export the Mysqldump tool to use with MySQL, the basic usage is:

Shell> mysqldump [OPTIONS] database [tables]

If you do not give any tables, the entire database will be exported.

By executing mysqldump--help, you can get a list of options supported by your mysqldump version.

Note that if you run mysqldump without the--quick or--opt option, mysqldump will load the entire result set into memory before exporting the results, which would probably be a problem if you are exporting a large database.

Mysqldump supports the following options:--Help Information--add-locks adds lock tables before each table is exported and then unlock table.    (To make it faster to insert into MySQL). --add-drop-table adds a drop table before each create statement. --allow-keywords allows you to create column names that are keywords.    This is done by prefixing the table name with each column name. -C,--complete-Insert uses the full INSERT statement (with the column name). -C,--Compress if both the client and the server support compression, compress all the information between the two. --delayed inserts a row with the insert delayed command. -E,--extended-Insert uses the new multiline insert syntax. (Give a more condensed and faster INSERT statement)-#,--debug[=option_string] Tracker usage (in order to debug). -F,--flush-logs before starting the export, wash the log files in the MySQL server. -F,--Force , even though we get a SQL error during the export of a table, continue. -H,--host=.. Export data from a MySQL server on a named host.    The default host is localhost. -L,--lock-tables.    Locks all tables for starting export. -T,--no-create-Infodo not write table creation information (CREATE TABLE statement)-D,--no-data does not write any row information for the table.    This is useful if you only want to export the structure of a table! --opt with--quick--add-drop-table--add-locks--extended-insert--lock-tables.    Should give you the fastest possible export for reading into a MySQL server. -pyour_pass,--password[=Your_pass] The password to use when connecting to the server. If you do not specify "=your_pass "section, Mysqldump requires a password from the terminal. -P Port_num,--port=port_num TCP used when connecting to a single host/IP port number. (This is used to connect to a host other than localhost because it uses a UNIX socket.) )-Q,--quick does not buffer queries, export directly to stdout; use Mysql_use_result () to do it. -s/path/to/socket,--socket=/path/to/Socket file used by the socket when connected to localhost (it is the default host). -T,--tab=path-to-some-directory for each given table, create a Table_name.sql file that contains the SQL create command, and a table_name.txt file that contains the data. Note: This only works when the mysqldump is running on the same machine as the mysqld daemon. The format of the. txt file is based on--fields-xxx and--lines--XXX option to set. -U user_name,--user=user_name The user name that MySQL uses when connecting to the server.    The default value is your UNIX login name. -O var=option,--set-variable var=option to set the value of a variable.    The possible variables are listed below. -V,--verbose verbose mode.    Print out more information that the program has done. -V,--version Prints the release information and exits. -W,--where='where-condition'only the selected records are exported; Note that the quotation marks are mandatory! "--where=user= ' JIMF '" "-wuserid>1" "-wuserid<1"
