deleterow()仅适用于可更新的结果集

我声明我的声明为 result.concur_update ,但如果我尝试使用 deleterow() 它显示的错误是 deleterow() 仅适用于 resultset.concur_updatable .

 public static void main(String args[]) throws 
 ClassNotFoundException,SQLException
{
    String driver="oracle.jdbc.OracleDriver";
    String url="jdbc:oracle:thin:@localhost:1521:XE";
    String user="system"; String pass="sysdb";
    Class.forName(driver);
    Connection con=DriverManager.getConnection(url,user,pass);
    Statement st=con.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
    String query="SELECT * FROM employees";
    ResultSet rs=st.executeQuery(query);
    System.out.println("S.No\tid\tname");
    while(rs.next())
    {
        System.out.print(rs.getRow()+"\t");
        System.out.print(rs.getString(1)+"\t");
        System.out.println(rs.getString("emp_name"));
    }
    rs.absolute(3);

    rs.deleteRow();
}

}
