使用NOT的MySQL查詢可能嗎？

Question

我有一個訂單狀態的數據庫'，我想返回該行的值是什麼，但完成的行數量。

我該怎麼辦？我有以下顯示有多少行具有「新」作爲訂單的狀態。但我想顯示od_status爲Complete的所有行。

<?php 
$query = "SELECT od_status FROM tbl_order WHERE od_status = 'New'"; 
$result = mysql_query($query) or die(mysql_error()); 
$num_rows = mysql_num_rows($result); 
echo "$num_rows"; 
?> 

Answer 1

<?php 
$query = "SELECT od_status FROM tbl_order WHERE od_status != 'Complete'"; 
$result = mysql_query($query) or die(mysql_error()); 
$num_rows = mysql_num_rows($result); 
echo "$num_rows"; 
?> 

Answer 2

$query = "SELECT od_status FROM tbl_order WHERE od_status <> 'Complete'"; 

Answer 3

$query = "SELECT COUNT(*) FROM tbl_order WHERE od_status != 'Complete'"; 
$result = mysql_query($query); 
var_dump($result); 

COUNT數行！=以選擇不等於完成。
