Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String driverName = "com.jnetdirect.jsql.JSQLDriver";
    Class.forName(driverName);/*from   ww w.  j a 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);
    Statement stmt = connection.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
    ResultSet resultSet = stmt.executeQuery("SELECT * FROM my_table");

    // Move cursor to the row to update
    resultSet.first();

    // Update the value of column col_string on that row
    resultSet.updateString("col_string", "new data");

    // Discard the update to the row
