Question

我希望加上金额+服务费+替换费用+街头费用+其他费用

但它不起作用请帮我解决这个问题感谢

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel,sum(amount) +  'servicecharges' + 'replacecharges' + 'blockcharges' + 'othercharges' AS amount,drivernamefuel FROM $tablename where carno='$c' AND monthdate BETWEEN '$a' AND '$b' GROUP BY monthdate";

请参阅ScreenShort 文件＃1：http://www.koolfree.com/ImageUpload/uploads/1381252318.jpg

显示这些错误警告：在第51行的indexssds.php中除以零

警告：mysql_fetch_array（）：提供的参数不是第73行indexssds.php中的有效MySQL结果资源

这里是完整的代码，请检查我的更新谢谢...........................

Answer 1

您没有传递参数进行查询，因此请将其传递到下面

而且你也没有添加
所选查询的SUM（..）中的金额+服务费+替换费用+冻结费+其他费用，所以一定要替换它

将您的查询修改为

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel,
   sum(amount +  servicecharges + replacecharges + blockingcharges + othercharges) AS amount,
   drivernamefuel 
   FROM ".$tablename." 
   WHERE carno='".$c."' AND monthdate BETWEEN '".$a."' AND '".$b."' 
   GROUP BY monthdate";

Answer 2

我希望这会对你有所帮助。删除qotes（'）并更改SUM（您想要求和的字段）

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel,sum(amount +  servicecharges + replacecharges + blockcharges + othercharges) AS total_amount,drivernamefuel FROM ".$tablename." where carno='".$c."' AND monthdate BETWEEN '".$a."' AND '".$b."' GROUP BY monthdate"; 

echo $sql;

在页面中回显查询并尝试直接在phpMyadmin中执行查询。然后检查查询的问题。问题可能是您要传递给查询的值

Answer 3

试试这个：

$sql="SELECT CONCAT(monthdate,' ','(',drivernamefuel,')') as drivernamefuel, 
SUM(amount +  
servicecharges + 
replacecharges + 
blockcharges + 
othercharges) AS amount,
drivernamefuel 
FROM ".$tablename." where carno='".$c."' 
AND monthdate BETWEEN '".$a."' AND '".$b."' 
GROUP BY monthdate";

*请注意mysql扩展名is now deprecated and will be removed sometime in the future。那是因为它古老，充满了不良做法，缺乏一些现代特色。不要用它来编写新代码。请改用PDO或mysqli_*。您的查询很容易SQL Injection。
