Question

如何将COUNT的结果回显到我的三个名为“已解决，重新分配和已关闭”的列？

我想计算已解决，已重新分配和已关闭的票证的数量，并将它们放入相应的列。我还需要总结每列和每行的总和。

这是一个票务系统，将通过严重性，类别2，类别3和状态上传。

所以在下图中，将生成每列中具有唯一值的报告，因此对于严重性5，我们在类别2下有两个条目，并且对于每个类别2，在类别3下将有不同的条目然后我想要显示多少对于类别3下的每个条目，票证已经解决，重新分配和关闭，例如，严重性5下的SMP_Backend有一个待处理请求而其他类别属于类别3，因此对于待处理订单，我们说已经解决了3并重新分配了2.我想要在Pending Request行中的Resolved和Re-assigned列下显示这些数字，我还想显示每行和每列的总数......

这是我的代码：

    <?php
require 'include/DB_Open.php';

$dates = $_POST['dates'];

$sql ="SELECT trouble_type_priority as `Severity`
    , category_1
    , category_2
    , SUM(IF(status='Resolved', 1, NULL)) as `Resolved`
    , SUM(IF(status='Re-assigned', 1, NULL)) as `Re-assigned`
    , SUM(IF(status IN ('Closed','Suspended'), 1, NULL)) as `Closed`
    , COUNT(status) as `Total`
    FROM tbl_main
    WHERE resolved_date = '$dates'
    GROUP BY Severity, category_1, category_2";

$myData = mysql_query($sql)or die(mysql_error());

$output = 
"<tr>
    <th colspan='3' align='center'>Ticket Bucket</th>
    <th colspan='3' align='center'>Status</th>
</tr>
<tr>
    <th width='auto' align='center'>Severity</th>

    <th width='auto' align='center'>Re-assigned</th>
    <th width='auto' align='center'>Closed</th>
    <th width='auto' align='center'>Grand Total</th>
</tr>\n";
$prev1 = $prev2 = $prev3 = '';
while (list($trouble_type_priority,$category_1,$category_2) = mysql_fetch_array($myData)) {

    if ($trouble_type_priority != $prev1) {
        $prCat1 = $trouble_type_priority;
        $prCat2 = $category_1;
        $prCat3 = $category_2;
        $prev1 = $trouble_type_priority; 
        $prev2 = $category_1;
        $prev3 = $category_2;
    }
    elseif ($category_1 != $prev2) {
        $prCat1 = '&nbsp';
        $prCat2 = $category_1;
        $prCat3 = $category_2;
        $prev2 = $category_1;
        $prev3 = $category_2;
    }
    elseif ($category_2 != $prev3) {

        $prCat2 = '&nbsp;';
        $prCat3 = $category_2;
        $prev3 = $category_2;
    }
    else $prCat1 = $prCat2 = $prCat3 = '&nbsp;';
    $output .= "<tr><td>$prCat1</td><td>$prCat2</td><td>$prCat3</td></tr>\n";

您要求的内容称为 pivot 查询。根据您的DBMS，可以使用PIVOT运算符或CASE语句来完成。像这样：

select id, resolved, closed, resolved + closed as total
from (
    select   id
           , max(case type when 'R' then Q else 0 end) as resolved
           , max(case type when 'C' then Q else 0 end) as closed
    from (
       select id, type, count(type) as Q
       from cases 
       group by id, type
    ) as A
) as B
