Question

有人可以帮助我从mysql表中获取数据。我想执行有关活动字段值的计算。 sql查询工作，但我无法在php页面中应用它。非常感谢你，我刚刚更改了查询结构代码，它仍然无法正常工作，你会看到什么：

<?php 
include_once('mysql_workbench.php'); 
$qryz="SELECT  Agent, Activity, format((PreTaxSalary), 2) as PreTaxSalary,    
format((TransactionNum), 2) as TransactionNum 

CASE attr(Activity)
When 'Eligibility Only (DDS)'
Then 
IF sum(TransactionNum)< 2206
Then sum(TransactionNum)*6.81
ElseIF sum(TransactionNum)< 2706
Then ((sum(TransactionNum)-2205)*6.95)+ (2205*6.81)
ElseIF sum(TransactionNum)< 3206
Then ((sum(TransactionNum)-2705)*7.25) + (500*6.95) + (2205*6.81) 
Else ((sum(TransactionNum)-3205)*7.85)+ (500*7.25) + (500*6.95)
+(2205*6.81)

END 
When 'EOB posting'
Then 
IF sum(TransactionNum)< 1786
Then sum(TransactionNum)*8.41
ElseIF sum(TransactionNum)< 2786
Then ((sum(TransactionNum)-1785)*9)+ (1785*8.41)
ElseIF sum(TransactionNum)< 3786
Then ((sum(TransactionNum)-2785)*9.75) + (1000*9) + (1785*8.41) 
Else ((sum(TransactionNum)-3785)*10.5)+ (1000*9.75) + (1000*9) +   
(1785*8.41)
END

When 'Trainee-1'
Then AVG(PreTaxSalary)*sum(TransactionNum)
When 'Trainee-1'
Then AVG(PreTaxSalary)*sum(TransactionNum)
When 'Trainee-2'
Then AVG(PreTaxSalary)*sum(TransactionNum)

END

from  payroll_trial group by Agent ";


?>
<tr>
<th >Agent</th>
<th >Activity</th>
<th >TransactionNum</th>
<th>PreTaxSalary</th>


</tr>
<?php
while($d=mysqli_fetch_array($resz))
{
?>
<td><?php echo $d['Agent'];?></td>
<td><?php echo $d['Client'];?></td> 
<td><?php echo $d['TransactionNum'];?></td> 
<td><?php echo $d['PreTaxSalary'];?> gdes </td> 
</tr>
<?php
 }

 ?>

Answer 1

我认为你的代码最大的问题是它不是PHP：）

我建议先学习如何用PHP编写代码。

但如果您想直接使用PHP中的Mysql，本教程可以帮助您http://www.w3schools.com/php/php_mysql_intro.asp

Answer 2

存储此代码的最佳方法是存储过程 https://dev.mysql.com/doc/refman/5.0/en/create-procedure.html

Answer 3

我终于找到了办法：

<?php 
include_once('mysql_workbench.php'); 
$qryz="SELECT  Agent, Activity, PreTaxSalary as    
PreT, SUM(TransactionNum) as totalTransaction from  payroll_trial;
$resz = @mysqli_query($dbc, $qryz);
?>
<tr>
 <th >Agent</th>
<th>Activity</th>
<th>Price</th>
<th>Amount</th>
<th>PreTaxSalary</th>


</tr>
<?php
while($d=mysqli_fetch_array($resz))
 {

$total=$d['totalTransaction'];
switch($d['Activity'])

{

case 'Reverification(DOP)':
IF ($total < 1366)
$total= $total*11;
ElseIF ($total < 1866)
$total=  (($total-1365)*11.65)+ (1365*11);
ElseIF ($total < 2366)
$total= (($total-1865)*13.2) + (500*11.65) + (1365*11); 
Else 
$total=  (($total-2365)*13.8)+ (500*13.2) + (500*11.65)
+ (1365*11);
break;

case 'Medicaid (CS)':
IF ($total < 2731)
$total= $total*5.5;
ElseIF ($total < 1866)
$total= (($total-3231)*2730)+ (2730*5.5);
ElseIF ($total < 3731) 
$total= (($total-3230)*6.8) + (500*6) + (2730*5.5) ; 
Else 
$total=  (($total-3730)*7.2)+  (500*6.8) + (500*6) +  
(2730*5.5);
break;
case 'Eligibility Only (DDS)':

IF ($total< 2206)
$total= $total*6.81;
ElseIF ($total< 2706)
$total= (($total-2205)*6.95)+ (2205*6.81);
ElseIF ($total < 3206)
$total= (($total-2705)*7.25) + (500*6.95) + (2205*6.81) ;
Else 
$total= (($total-3205)*7.85)+ (500*7.25) + 
(500*6.95) + (2205*6.81);
break;
?>
<tr>
<td><?php echo $d['Agent'];?></td> 
<td><?php echo $d['Activity'];?></td> 
<td><?php echo $d['totalTransaction '];?> </td> 
</tr>
<td><?php echo $d['PreT'];?> </td>
