A command-line interface is a means of interacting with a computer program where the user issues commands to the program by typing in successive lines of text (command lines). MySQL ships with many command line tools, from which the main interface is the mysql client.[112][113]

The database user you specify when you add the data source should only be granted SELECT permissions onthe specified database and tables you want to query. Grafana does not validate that the query is safe. The querycould include any SQL statement. For example, statements like USE otherdb; and DROP TABLE user; would beexecuted. To protect against this we Highly recommend you create a specific mysql user with restricted permissions.

Specifies a query that the connector executes on the source database when the connector sends a heartbeat message.


For example, this can be used to periodically capture the state of the executed GTID set in the source database.


INSERT INTO gtid_history_table (select * from mysql.gtid_executed)

To deliver a managed service experience, Amazon RDS doesn't provide shell access to DB instances. It also restricts access to certain system procedures and tables that need advanced privileges. You can access your database using standard SQL clients such as the mysql client. However, you can't access the host directly by using Telnet or Secure Shell (SSH).

rejectReadOnly=true causes the driver to reject read-only connections. Thisis for a possible race condition during an automatic failover, where the mysqlclient gets connected to a read-only replica after the failover.

Server public keys can be registered with mysql.RegisterServerPubKey, which can then be used by the assigned name in the DSN.Public keys are used to transmit encrypted data, e.g. for authentication.If the server's public key is known, it should be set manually to avoid expensive and potentially insecure transmissions of the public key from the server to the client each time it is required.

tls=true enables TLS / SSL encrypted connection to the server. Use skip-verify if you want to use a self-signed or invalid certificate (server side) or use preferred to use TLS only when advertised by the server. This is similar to skip-verify, but additionally allows a fallback to a connection which is not encrypted. Neither skip-verify nor preferred add any reliable security. You can use a custom TLS config after registering it with mysql.RegisterTLSConfig.

Files must be explicitly allowed by registering them with mysql.RegisterLocalFile(filepath) (recommended) or the allowlist check must be deactivated by using the DSN parameter allowAllFiles=true (Might be insecure!).

To use a io.Reader a handler function must be registered with mysql.RegisterReaderHandler(name, handler) which returns a io.Reader or io.ReadCloser. The Reader is available with the filepath Reader:: then. Choose different names for different handlers and DeregisterReaderHandler when you don't need it anymore.

If your settings do not match any list you will have to edit the MySQL configuration file. On Linux this may be /etc/my.cnf, /etc/mysql/my.cnf, or /etc/my.cnf.d/mariadb-server.cnf; on Microsoft Windows it may be my.ini.

This is the MySQL API module for Ruby. It provides the same functions for Rubyprograms that the MySQL C API provides for C programs.This package is offered as gem for easy installation using RubyGems. It wrapsunmodified tmtm's mysql-ruby extension into a proper gem.Please note that tmtm (Tomita Mashahiro) has deprecated development of thisextension and only update it for bug fixes.

Please note: once you are using a dedicated ClearDB MySQL environment, you cannot downgrade back into a ClearDB shared MySQL database. Instead, you will need to manually backup and restore your database into a ClearDB shared database using traditional MySQL tools, such as the mysqldump and mysql command line tools, or MySQL Workbench.

Please see the PHP documentation for using certificate files in the mysqli module. In that documentation $key should be set to the contents of the Client Private Key file, $cert to Client Certificate and $ca to ClearDB CA Certificate.

The following manifest describes a single-instance MySQL Deployment. The MySQLcontainer mounts the PersistentVolume at /var/lib/mysql. The MYSQL_ROOT_PASSWORDenvironment variable sets the database password from the Secret.

We have two MariaDB databases for public access: genome-mysql.soe.ucsc.edu (located on the US west coast) genome-euro-mysql.soe.ucsc.edu (located in Europe)

Learn about how you can load data faster with streaming replication, how to use the new system tables in the mysql database, how your application can benefit from the new synchronization functions, and how Galera Cluster is now so much more robust in handling a bad network for Geo-distributed Multi-master MySQL.

Spring Initializr creates a simple class for the application. The following listing shows the class that Initializr created for this example (in src/main/java/com/example/accessingdatamysql/AccessingDataMysqlApplication.java): 17dc91bb1f
