Mam taki błąd podczas próby połączenia i pobrania danych z mojej bazy danych.

Metoda executeQuery () nie może przyjmować argumentów w PreparedStatement lub CallableStatement.

Mój kod wygląda tak.

String search = request.getParameter("searchstudent");
out.println(search);

String connectionURL = "jdbc:sqlserver://localhost:1433;databaseName=Chingdb;   integratedSecurity=true;";
 Connection connection = null;
 PreparedStatement pstatement = null;
 Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
 ResultSet rs = null;
int updateQuery = 0;


if(request.getParameter("editstudent")!= null){ 
    try {           
     connection = DriverManager.getConnection(connectionURL, "root", "root");
     String queryString = "SELECT P_ID, lname, fname, mname FROM stu_info Where lname = ?";
     pstatement = connection.prepareStatement(queryString);
     pstatement.setString(1, search);
     rs = pstatement.executeQuery(queryString);
        updateQuery = pstatement.executeUpdate();
        %>
        <TABLE cellpadding="15" border="1" style="background-color: #ffffcc;">
        <%
        while (rs.next()) {
        %>
        <TR>
        <TD><%=rs.getInt(1)%></TD>
        <TD><%=rs.getString(2)%></TD>
        <TD><%=rs.getString(3)%></TD>
        <TD><%=rs.getString(4)%></TD>
        </TR></TABLE>
        <% 

        rs.close();
        pstatement.close();
        connection.close();

        }
        }

    catch(Exception e){
    out.println(e);
    }

   }
