Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    Connection dbConnection = null;
    PreparedStatement preparedStatement = null;
    Class.forName(DB_DRIVER);//from w w  w . j a  v a 2 s. c om
    dbConnection = DriverManager.getConnection(DB_CONNECTION, DB_USER, DB_PASSWORD);
    String deleteSQL = "DELETE Person WHERE USER_ID = ?";
    preparedStatement = dbConnection.prepareStatement(deleteSQL);
    preparedStatement.setInt(1, 1001);

    preparedStatement.executeUpdate();
