JDBC中调用PreparedStatement的用法报错

Question

初学JDBC，调用PreparedStatement对象的executeUpdate方法，提示 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%'''，请求前辈支援。以下为代码    private static int UpdateScore(Object... params) throws Exception {        int result = 0;         String sql = "UPDATE student SET score=? WHERE  sex=? and NAME LIKE ''?%'';";         Connection connection = JDBCUtil.getConnection();         PreparedStatement preparedStatement = connection.prepareStatement(sql);         preparedStatement.setInt(1, Integer.parseInt(params[0].toString()));         preparedStatement.setString(2, params[1].toString());         preparedStatement.setString(3, params[2].toString());         result = preparedStatement.executeUpdate();        return result;     }
