Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String driverName = "com.jnetdirect.jsql.JSQLDriver";
    Class.forName(driverName);/*  www  . ja v  a 2 s .  c  o  m*/

    String serverName = "127.0.0.1";
    String portNumber = "1433";
    String mydatabase = serverName + ":" + portNumber;
    String url = "jdbc:JSQLConnect://" + mydatabase;
    String username = "username";
    String password = "password";

    Connection connection = DriverManager.getConnection(url, username, password);
    // Create a scrollable result set
    Statement stmt = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY);
    ResultSet resultSet = stmt.executeQuery("SELECT * FROM my_table");

    // Move cursor forward
    while (resultSet.next()) {
        // Get data at cursor
