How to display selected value from dropdown in wordpress

I have state table having state_id and state_name. I am displaying it directly in template file like below..

  <select name="state"  id="state"  class="select-submit2">
   <option  value="">Select state</option>
  <?php 
    $result=$wpdb->get_results("select * from states");
    foreach($result as $row) {
        $state_id=$row->state_id;
        $state_name=$row->state_name;
        echo '<option value='.$state_id.'>'.$state_name.'</option>';
    }
   ?>     
</select>

But when I want to edit that how do I show first selected state name.????

Edit page url... whitecode.in/demo/plotsup_plot/new-property/?listing_edit=6795

This is my function code in function.php file

   function getcity(){
      global $wpdb;
       if($_POST['state'])
            {
                $id=$_POST['state'];
                $property_id = $_GET['listing_edit']; 
                                     $district = get_post_meta($property_id, district, true);
                $result=$wpdb->get_results("SELECT * FROM districts WHERE state_id='$id'");
                //$wpdb->get_results($query);
                              foreach($result as $row) {
                                                             $city_name   = $row->district_name;
                             $city_id     = $row->district_id;
                        ?>
     <option value="<?php echo $city_id; ?>" <?php if($district == $city_id){ echo 
  'selected="selected"';} ?>><?php echo $city_name; ?></option>
  <?php      
                              //echo '<option value="'.$city_id.'">'.$city_name.'</option>';


            }
   } 
   }

As per as discussed in the previous comments, I guess that property is a custom post type in your site. So if that is the scenario then this should be the solution.

<select name="state"  id="state"  class="select-submit2">
<option  value="">Select state</option>
<?php 
$property_id = $_GET['listing_edit']; //the PROPERTY_ID should be replaced with the original id might be ina get variable or any process by which you are using for the edit page.
$property_state = get_post_meta($property_id, META_KEY_STATE, true); //META_KEY_STATE is the meta_key name you use to store the value of the state in the postmeta table
$result=$wpdb->get_results("select * from states");
foreach($result as $row) {
    $state_id=$row->state_id;
    $state_name=$row->state_name;
    ?>
    <option value="<?php echo $state_id; ?>" <?php if($property_state == $state_id){ echo 'selected="selected"';} ?>><?php echo $state_name; ?></option>
    <?php
}
?>     
</select>

Try this and let me know if you face any issues.

If this is what you are looking for?

<select name="state"  id="state"  class="select-submit2">
   <option  value="">Select state</option>
   <?php 
    $result=$wpdb->get_results("select * from states");
    foreach($result as $row) {
         $state_id=$row->state_id;
         $state_name=$row->state_name;
         if($state_id == SELECTED_STATE_ID)
             echo '<option value='.$state_id.' selected>'.$state_name.'</option>';
         else
             echo '<option value='.$state_id.'>'.$state_name.'</option>';
     }
   ?>     
</select>

just replace SELECTED_STATE_ID with variable which contains which state is selected
