Take some insight on the salt water evaporates

I've the next bit of code

  public static void updateOrdersPrepared(int productId , String productName){

    Connection con = getConnection();

    try {
            pstmt = con.prepareStatement 
                  ("update Orders set productname = ? where Prod_Id  = ?");

            pstmt.setInt(2, productId);
            pstmt.setString(1, productName);
            pstmt.executeUpdate();
            pstmt.close();
            con.close();

    } catch(SQLException ex) {
        System.err.println("SQLException: " + ex.getMessage());
    }
JOptionPane.showMessageDialog(null,"Data Updated into Orders Table");
}

If this process is known as 'N' quantity of occasions , will the query arrange for the prepared statement be calculated 'N' occasions or simply once ?

It is possible to real benefit of using prepared claims such situations ?

It'll rely on the RDBMS you're focusing on.

SQL Server has the capacity to cache a parameterised query arrange for the statement "update Orders set productname = ? where Prod_Id = ?" so you will see an advantage. However, it's this type of simple query the benefit will probably be quite small.

You need to measure inside your particular conditions (is the server CPU bound, or I/O bound? It's often the second).

When you are aware. the actual benefit to utilizing a PreparedStatement is planning it once after which calling many occasions with various parameters set.
