X DevAPI User Guide  /  ...  /  Connecting to a Single MySQL Server

2.2.1 Connecting to a Single MySQL Server

In this example a connection to a local MySQL Server instance running X Plugin on the default TCP/IP port 33060 is established using the MySQL user account user with its password. As no other parameters are set, default values are used.

MySQL Shell JavaScript Code

Press CTRL+C to copy
// Passing the parameters in the { param: value } format var dictSession = mysqlx.getSession( { host: 'localhost', 'port': 33060, user: 'user', password: 'password' } ) var db1 = dictSession.getSchema('test') // Passing the parameters in the URI format var uriSession = mysqlx.getSession('user:password@localhost:33060') var db2 = uriSession.getSchema('test')

MySQL Shell Python Code

Press CTRL+C to copy
# Passing the parameters in the { param: value } format dictSession = mysqlx.get_session( { 'host': 'localhost', 'port': 33060, 'user': 'user', 'password': 'password' } ) db1 = dictSession.get_schema('test') # Passing the parameters in the URI format uriSession = mysqlx.get_session('user:password@localhost:33060') db2 = uriSession.get_schema('test')

The following example shows how to connect to a single MySQL Server instance by providing a TCP/IP address localhost and the same user account as before. You are prompted to enter the user name and password in this case.

MySQL Shell JavaScript Code

// Passing the parameters in the { param: value } format // Query the user for the account information print("Please enter the database user information."); var usr = shell.prompt("Username: ", {defaultValue: "user"}); var pwd = shell.prompt("Password: ", {type: "password"}); // Connect to MySQL Server on a network machine mySession = mysqlx.getSession( { host: 'localhost', 'port': 33060, user: usr, password: pwd} ); myDb = mySession.getSchema('test');
