嗨，大家好，你能幫助我，我不知道該代碼如何在我的SQL數據庫中添加的行值。（見上面的例子）

我有這樣的代碼，這將算我有多少條記錄

<input type="text" name="namesearch" size="5" tabindex="1" /> 

<input type="submit" name='click' value='Search' /> 


if(isset($_POST['click'])){ 


    $name= $_POST['namesearch']; 
    $query = "SELECT COUNT(*) AS total FROM table WHERE name='$name'"; 
    $result = mysql_query($query); 
    $values = mysql_fetch_assoc($result); 
    $num_item= $values['total']; 
    echo "Number of Records Found # ".$num_item; 

Answer 1

以此爲查詢

$query = "SELECT COUNT(*) AS total, SUM(money) AS total_money FROM table WHERE name='$name'"; 

使用此功能查看結果

$num_item = $values['total']; 
$total_value = $values['total_money']; 
echo "Number of Records Found # ".$num_item; 
echo "Total Money ".$total_value 

Answer 2

由於我的MySQL服務器在升級操作系統後丟失了，不要相信語法（lol）。試試這個：

SELECT COUNT(*), SUM(`money`) AS `total_money` FROM `my_table` GROUP BY `name`; 

這應該（？）給你每個名字的行數，它是總金額的總和。

Answer 3

使用MySQL SUM Function

SELECT SUM(money) AS total FROM table WHERE name='$name'
