使用NOT的MySQL查询可能吗？

Question

我有一个订单状态的数据库'，我想返回该行的值是什么，但完成的行数量。

我该怎么办？我有以下显示有多少行具有“新”作为订单的状态。但我想显示od_status为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数行！=以选择不等于完成。
