php mysql จะแสดงวันที่ปัจจุบัน ให้อยู่บนสุดของตาราง ทำอย่างไรค่ะ

<?php
$sql=" select * from tb_delivery order by deli_datejob desc ";
              
if(isset($_POST['search']))
              {
                  $txt_search=$_POST['txt_search'];
                  $sql.=" where";
                  $sql.=" deli_name like '%".$txt_search."%'";
                  $sql.=" or";
                  $sql.=" deli_detail like '%".$txt_search."%'"; 
              }
              
            
					$result = $conn->query($sql);
					if ($result->num_rows > 0) {

						while($row = $result->fetch_assoc()) {
							echo "<tr>";
																
								echo "<td>" . $row["deli_wan"]. "</td>";							
								echo "<td>" . $row ["deli_datejob"]. "</td>";
								echo "<td>" . $row["deli_name"]. "</td>";																								
								echo "<td>" . $row["deli_detail"]. "</td>";

						}
					}
					
?>
