How to connect applications to Azure Database for MariaDB

This topic lists the connection string types that are supported by Azure Database for MariaDB, together with templates and examples. You might have different parameters and settings in your connection string.

• To obtain the certificate, see How to configure SSL.
• {your_host} = [servername].mariadb.database.chinacloudapi.cn
• {your_user}@{servername} = userID format for authentication correctly. If you only use the userID, the authentication will fail.

ADO.NET

Server={your_host}; Port=3306; Database={your_database}; Uid={username@servername}; Pwd={your_password}; SslMode=Preferred;

In this example, the server name is mydemoserver, the database name is wpdb, the user name is WPAdmin, and the password is mypassword!2. As a result, the connection string should be:

Server= "mydemoserver.mariadb.database.chinacloudapi.cn"; Port=3306; Database= "wpdb"; Uid= "WPAdmin@mydemoserver"; Pwd="mypassword!2"; SslMode=Required;

JDBC

String url ="jdbc:mariadb://{your_host}:3306/{your_database}?useSSL=true&trustServerCertificate=true"; myDbConn = DriverManager.getConnection(url, "{username@servername}", {your_password});

Node.js

var conn = mysql.createConnection({host: "{your_host}", user: "{your_username}", password: {your_password}, database: {your_database}, port: 3306, ssl:{ca:fs.readFileSync({ca-cert filename})}});

ODBC

DRIVER={MARIADB ODBC 3.0 Driver}; Server="{your_host}"; Port=3306; Database={your_database}; Uid="{username@servername}"; Pwd={your_password}; sslca={ca-cert filename}; sslverify=1;

PHP

$con=mysqli_init(); mysqli_ssl_set($con, NULL, NULL, {ca-cert filename}, NULL, NULL); mysqli_real_connect($con, "{your_host}", "{username@servername}", {your_password}, {your_database}, 3306);

Python

cnx = mysql.connector.connect(user="{username@servername}", password={your_password}, host="{your_host}", port=3306, database={your_database}, ssl_ca={ca-cert filename}, ssl_verify_cert=true)

Ruby

client = Mysql2::Client.new(username: "{username@servername}", password: {your_password}, database: {your_database}, host: "{your_host}", port: 3306, sslca:{ca-cert filename}, sslverify:false, sslcipher:'AES256-SHA')

Get the connection string details from the Azure portal

In the Azure portal, go to your Azure Database for MariaDB server, and then select Connection strings to get the string list for your instance:

The string provides details such as the driver, server, and other database connection parameters. Modify these examples to use your own parameters, such as database name, password, and so on. You can then use this string to connect to the server from your code and applications.
