Connect to data.world datasets using the JDBC driver dw-jdbc

JDBC connects to data source based on a provided JDBC url. data.world JDBC urls have the form

jdbc:data:world:[language]:[user id]:[dataset id]

where [language] is either "sql" or "sparql",[user id] is the data.world id of the dataset owner, and [dataset id] is the data.world identifier for the dataset.

final String QUERY = "select * from HallOfFame where playerID = ? order by yearid, playerID limit 10"
final String URL = "jdbc:data:world:sql:dave:lahman-sabremetrics-dataset";
try (final Connection connection = // get a connection to the database, which will automatically be closed when done
             DriverManager.getConnection(URL, "<your user name>", "<your API token>");
     final PreparedStatement statement = // get a connection to the database, which will automatically be closed when done
             connection.prepareStatement(QUERY)) {
    statement.setString(1, "alexape01"); //bind a query parameter
    try (final ResultSet resultSet = statement.executeQuery()) { //execute the query
        ResultSetMetaData rsmd = resultSet.getMetaData();  //print out the column headers
        int columnsNumber = rsmd.getColumnCount();
        for (int i = 1; i <= columnsNumber; i++) {
            if (i > 1) System.out.print(",  ");
            System.out.print(rsmd.getColumnName(i));
        }
        System.out.println("");
        while (resultSet.next()) { //loop through the query results
            for (int i = 1; i <= columnsNumber; i++) { //print out the column headers
                if (i > 1) System.out.print(",  ");
                String columnValue = resultSet.getString(i);
                System.out.print(columnValue);
            }
            System.out.println("");
        }
    }
}

dw-jdbc can be built from the command-line using mvn clean install.

When you need an API token for an integration, you can get it from your profile settings. Click on your user icon and choose Settings:

Both Read/Write and Admin tokens are provided. For the metadata catalog collector you can use the Read/Write token for the metadata catalog collector if you have write permissions to your organization's ddw-catalogs dataset.
