MySQL JDBC for Linux

This tutorial shows how to set up a data source and connect to a MySQL® database using the Database Explorer app or the command line. This tutorial uses the MySQL Connector/J 5.1.46 driver to connect to a MySQL Version 5.5.16 database.

Step 1. Verify the driver installation.

If the JDBC driver for MySQL is not installed on your computer, find the link on the Driver Installation page to install the driver. Follow the instructions to download and install this driver on your computer.

Step 2. Set up the data source.

You set up a data source using the Database Explorer app or the command line.

Set Up Data Source Using Database Explorer

  1. Open the Database Explorer app by clicking the Apps tab on the MATLAB® Toolstrip. Then, on the right of the Apps section, click the Show more arrow to open the apps gallery. Under Database Connectivity and Reporting, click Database Explorer. Alternatively, enter databaseExplorer at the command line.

  2. In the Data Source section, select Configure Data Source > Configure JDBC data source.

    The JDBC Data Source Configuration dialog box opens.

  3. In the Name box, enter a name for your data source. (This example uses a data source named MySQL.) You use this name to establish a connection to your database.

  4. From the Vendor list, select MySQL.

  5. In the Driver Location box, enter the full path to the JDBC driver file.

  6. In the Database box, enter the name of your database. In the Server box, enter the name of your database server. Consult your database administrator for the name of your database server. In the Port Number box, enter the port number.

  7. Under Connection Options, in the Name column, enter the name of an additional driver-specific option. Then, in the Value column, enter the value of the driver-specific option. Click the plus sign + to specify additional driver-specific options.

  8. Click Test. The Test Connection dialog box opens. Enter the user name and password for your database, or leave these boxes blank if your database does not require them. Click Test.

    If your connection succeeds, the Database Explorer dialog box displays a message indicating the connection is successful. Otherwise, it displays an error message.

  9. Click Save. The JDBC Data Source Configuration dialog box displays a message indicating the data source is saved successfully. Close this dialog box.

Set Up Data Source Using Command Line

  1. Create a JDBC data source for a MySQL database.

    vendor = "MySQL";
    opts = databaseConnectionOptions("jdbc",vendor);
  2. Set the JDBC connection options. For example, this code assumes that you are connecting to a JDBC data source named MySQL, full path of the JDBC driver file /home/user/DB_Drivers/mysql-connector-java-5.1.17-bin.jar, database name toystore_doc, database server dbtb01, and port number 3306.

    opts = setoptions(opts, ...
        'DataSourceName',"MySQL", ...
        'JDBCDriverLocation',"/home/user/DB_Drivers/mysql-connector-java-5.1.17-bin.jar", ...
        'DatabaseName',"toystore_doc",'Server',"dbtb01", ...
        'PortNumber',3306);
  3. Test the database connection by specifying the user name username and password pwd, or leave these arguments blank if your database does not require them.

    username = "username";
    password = "pwd";
    status = testConnection(opts,username,password);
  4. Save the JDBC data source.

    saveAsDataSource(opts)

After you complete the data source setup, connect to the MySQL database using the Database Explorer app or the JDBC driver and command line.

Step 3. Connect using the Database Explorer app or the command line.

Connect to MySQL Using Database Explorer App

  1. On the Database Explorer tab, in the Connections section, click Connect and select the data source for the connection.

  2. In the connection dialog box, enter a user name and password, or leave these boxes blank if your database does not require them. Click Connect.

    The Catalog and Schema dialog box opens.

  3. In the Catalog list, select the catalog. Click OK.

    The app connects to the database and displays its tables in the Data Browser pane. A data source tab appears to the right of the pane. The title of the data source tab is the data source name that you defined during the setup. The data source tab contains empty SQL Query and Data Preview panes.

  4. Select tables in the Data Browser pane to query the database.

  5. Close the data source tab to close the SQL query. In the Connections section, close the database connection by clicking Close Connection.

    Note

    If multiple connections are open, close the database connection of your choice by selecting the corresponding data source from the Close Connection list.

Connect to MySQL Using JDBC Driver and Command Line

  1. Connect to a MySQL database using the configured JDBC data source, user name username, and password pwd.

    datasource = "MySQL";
    username = "username";
    password = "pwd";
    conn = database(datasource,username,password);
  2. Close the database connection.

    close(conn)
