The output can be exported to file using the following command —. Let us consider one example, we will firstly query on my database server to display all databases —.
Note that we will have to exit from the MySQL command shell and then execute the above command. After, a file named backupOfEducba.
After opening the file, we will see that it contains all the commands of SQL that will recreate the educba database in case if we restore this file to a certain database.
This is the dumped flat-file created after dumping the educba file that contains the command of create a database, create a table and insert queries to insert the records in the table. We can see that the educba database does not exist in our database server of MySQL. Now, we will restore the educba database from the backup file backupOfEducba.
Here we also discuss the introduction and syntax of mysql dump along with different examples and its code implementation. Submit Next Question.

Certain options might require other privileges as noted in the option descriptions.
To reload a dump file, you must have the privileges required to execute the statements that it contains, such as the appropriate CREATE privileges for objects created by those statements. These may be used when dumping stored programs to preserve their character encodings.
To reload a dump file containing such statements, the ALTER privilege for the affected database is required. However, UTF is not permitted as a connection character set see Impermissible Client Character Sets , so the dump file cannot be loaded correctly.
You can clone databases for development and DBA work, or produce slight variations of an existing database for testing. It is not intended as a fast or scalable solution for backing up substantial amounts of data.
For large-scale backup and restore, a physical backup is more appropriate, to copy the data files in their original format that can be restored quickly:. Available as part of the Enterprise subscription. It provides the best performance for InnoDB backups with minimal disruption; it can also back up tables from MyISAM and other storage engines; and it provides a number of convenient options to accommodate different backup scenarios.
See Section Buffering in memory can be a problem if you are dumping large tables. To dump tables row by row, use the --quick option or --opt , which enables --quick. The --opt option and hence --quick is enabled by default, so to enable memory buffering, use --skip-quick.
If you are using a recent version of mysqldump to generate a dump to be reloaded into a very old MySQL server, use the --skip-opt option instead of the --opt or --extended-insert option. For additional information about mysqldump , see Section 7. There are in general three ways to use mysqldump —in order to dump a set of one or more tables, a set of one or more complete databases, or an entire MySQL server—as shown here:.
To see a list of the options your version of mysqldump supports, issue the command mysqldump --help. The mysqldump command logs into a MySQL server to extract information. The following options specify how to connect to the MySQL server, either on the same machine or a remote system. On a computer having multiple network interfaces, use this option to select which interface to use for connecting to the MySQL server. Compress all information sent between the client and the server if possible.
See Section 4. As of MySQL 8. Expect it to be removed in a future version of MySQL. See Configuring Legacy Connection Compression. The permitted compression algorithms for connections to the server. The default value is uncompressed. For more information, see Section 4.
A hint about which client-side authentication plugin to use. See Section 6. Request from the server the public key required for RSA key pair-based password exchange. For that plugin, the server does not send the public key unless requested. This option is ignored for accounts that do not authenticate with that plugin. It is also ignored if RSA-based password exchange is not used, as is the case when the client connects to the server using a secure connection.
Dump data from the MySQL server on the given host. The default host is localhost. Read options from the named login path in the. For additional information about this and other option-file options, see Section 4. The password of the MySQL account used for connecting to the server.
The password value is optional. If not given, mysqldump prompts for one. If no password option is specified, the default is to send no password. Specifying a password on the command line should be considered insecure. To avoid giving the password on the command line, use an option file.
To explicitly specify that there is no password and that mysqldump should not prompt for one, use the --skip-password option. The password for multifactor authentication factor 1 of the MySQL account used for connecting to the server. To explicitly specify that there is no password and that mysqldump should not prompt for one, use the --skip-password1 option. The password for multifactor authentication factor 2 of the MySQL account used for connecting to the server.
The semantics of this option are similar to the semantics for --password1 ; see the description of that option for details. The password for multifactor authentication factor 3 of the MySQL account used for connecting to the server. On Windows, connect to the server using a named pipe.
The directory in which to look for plugins. Specify this option if the --default-auth option is used to specify an authentication plugin but mysqldump does not find it. The transport protocol to use for connecting to the server. It is useful when the other connection parameters normally result in use of a protocol other than the one you want. For details on the permissible values, see Section 4. The path name to a file in PEM format containing a client-side copy of the public key required by the server for RSA key pair-based password exchange.
This option is ignored for accounts that do not authenticate with one of those plugins. Do not drop the mysql schema when the dump file is restored. By default, the schema is dropped.
For connections to localhost , the Unix socket file to use, or, on Windows, the name of the named pipe to use. Options that begin with --ssl specify whether to connect to the server using encryption and indicate where to find SSL keys and certificates. See Command Options for Encrypted Connections.
Controls whether to enable FIPS mode on the client side. The --ssl-fips-mode option differs from other --ssl- xxx options in that it is not used to establish encrypted connections, but rather to affect which cryptographic operations to permit. These --ssl-fips-mode values are permitted:. The permissible ciphersuites for encrypted connections that use TLSv1. The value is a list of one or more colon-separated ciphersuite names.
For details, see Section 6. The permissible TLS protocols for encrypted connections. The value is a list of one or more comma-separated protocol names. The compression level to use for connections to the server that use the zstd compression algorithm.
The permitted levels are from 1 to 22, with larger values indicating increasing levels of compression. The default zstd compression level is 3. The compression level setting has no effect on connections that do not use zstd compression.
Read this option file after the global option file but on Unix before the user option file. If the file does not exist or is otherwise inaccessible, an error occurs. Use only the given option file.
Exception: Even with --defaults-file , client programs read. Read not only the usual option groups, but also groups with the usual names and a suffix of str. For example, mysqldump normally reads the [client] and [mysqldump] groups. Do not read any option files. If program startup fails due to reading unknown options from an option file, --no-defaults can be used to prevent them from being read.
The exception is that the. This permits passwords to be specified in a safer way than on the command line even when --no-defaults is used. To create. Usage scenarios for mysqldump include setting up an entire new MySQL instance including database tables , and replacing data inside an existing instance with existing databases and tables. The following options let you specify which things to tear down and set up when restoring a dump, by encoding various DDL statements within the dump file.
In MySQL 8. Instead, to use --add-drop-database , use --databases with a list of schemas to be dumped, where the list does not include mysql. This information is not otherwise included in the output from mysqldump. This option is currently relevant only to NDB Cluster tables. This option does not exclude statements creating log file groups or tablespaces from mysqldump output; however, you can use the --no-tablespaces option for this purpose. The following options print debugging information, encode debugging information in the dump file, or let the dump operation proceed regardless of potential problems.
Permit creation of column names that are keywords. This works by prefixing each column name with the table name.
