Connection parameters Parameter nameĪ SQL user to connect to the TiDB clusterįor more information about TiDB SQL users, see TiDB User Account Management. And for connectivity with JDBC, I need the URL, host and port number. Hibernate supports TiDB dialects starting from 6.0.0.Beta2, so it is recommended that you use Hibernate 6.0.0.Beta2 or a later version to connect to TiDB.įor more information about Hibernate connection parameters, see Hibernate documentation. When I open the MySQL command line client, it only asks me for my password.It is recommended that you use the TiDB dialect by setting hibernate.dialect to.For example, you need to change the connection string from jdbc:mysql://. Because the configuration file is in the XML format and & is a special character in XML, you need to change & to & when configuring the file.It is possible to specify connection parameters without entering them on the command line every time a client program is invoked.SessionFactory sessionFactory = new Configuration().configure( "").buildSessionFactory() It can be done using any one of the way − mysql -port=13306 -host=127.0.0.1 To cause the port number to be used, force a TCP/IP connection. Lets see how it can be done − mysql -host= -port=13306 To specify a port number explicitly, the -port or -P option can be used. The command would connect to the server running on using the default port number (3306). (period) can also be mentioned as the host name.Ĭonnections to remote servers will use TCP/IP. This can be done by specifying the -pipe or -protocol=PIPE option. On Windows, MySQL client can be forced to use a named-pipe connection. Let us see with the example − Example mysql -host=127.0.0.1 The transport protocol can be explicitly mentioned using the -protocol=TCP option. Instead of this, the IP address or name of the local server can also be mentioned. To ensure that the client makes a TCP/IP connection to the local server, ‘-host’ or ‘-h’ needs to be specified, with a host name value of 127.0.0.1 (instead of localhost). If the host is not specified or it is a localhost, a connection to the local host occurs Mysql -h localhost -u myname -ppassword mydbĬlient programs determine the type of connection that needs to be made − Let us see this with the command − mysql -host=localhost -user=myname -password=password mydb To select a default database, add a database-name argument. To specify the host name, user name and password specifically, provide appropriate options on the command line. Since there is no such argument, mysql selects no default database. No password is sent because neither -password nor -p has been mentioned.įor mysql, the first non-option argument is considered the name of the default database. To start multiple servers this way, you can specify the appropriate options on the command line or in an option file. The default user name is ODBC on Windows. The procedure for starting a single MySQL server manually from the command line is described in Section 2.3.4.6, Starting MySQL from the Windows Command Line. Since there are no parameter options, the default values will be applied − The below command invokes mysql without specifying any explicit connection parameters − mysql Using MySQL Client Services First, we can quickly get the port information from the global variables of the MySQL services. This is done for clients like mysql or mysqldump. Once you find the file, open it with any text editor and add the following line: Port 3242. In this demo, the location of that directory is C:\MySQLHome. The my.ini file is in the MySQL Home directory. Let us understand how MySQL can be connected to the database using the command-line. We can change the default port by editing the my.ini configuration file.
