这是我一直在使用的一小段代码。
<?php
$rank = 0;
$rank = 0;
$sql = mysql_query("SELECT m.memberID, username,email,target,type, ifnull(t.total,0) as total, ifnull(m.total,0) as totalp FROM `members` as m
left join (
select s.memberID, sum(amount) total from sponsors as s group by s.memberID
) t on t.memberid = m.memberid
left join (
select s.memberID, sum(amount) total from sponsors as s group by s.memberID
) p on p.memberid = m.memberid Where type= 'business'
ORDER BY t.total DESC, p.total DESC, username ASC");
while($row = mysql_fetch_object($sql))
{
echo "<tr>";
$rank = $rank + 1;
echo "<td><center>$rank</center></td>";
echo "<td>$row->username</td>";
echo "<td>$row->total</td>";
echo "<td>$row->target</td>";
echo "<td>$row->here i want percentage</td>";
echo "</tr>";
}
?>
我想做的是在表的最后一列中显示total/target的百分比。我不知道最好的方法是什么，我很想听到一些想法。
我确实尝试过这样做，就像总/目标在回声中，但认为它可能需要作为一个变量或其他东西进行评估?不管我怎么试都没用……
看了这个，但不确定如何在我的场景中实现它- MSSQL显示百分比从两列计算
试试这个，
<?php
$rank = 0;
$rank = 0;
$sql = mysql_query("SELECT m.memberID, username,email,target,type, ifnull(t.total,0) as total, ifnull(m.total,0) as totalp, (ifnull(t.total,0)/target)*100 as present FROM `members` as m
left join (
select s.memberID, sum(amount) total from sponsors as s group by s.memberID
) t on t.memberid = m.memberid
left join (
select s.memberID, sum(amount) total from sponsors as s group by s.memberID
) p on p.memberid = m.memberid Where type= 'business'
ORDER BY t.total DESC, p.total DESC, username ASC");
while($row = mysql_fetch_object($sql))
{
echo "<tr>";
$rank = $rank + 1;
echo "<td><center>$rank</center></td>";
echo "<td>$row->username</td>";
echo "<td>$row->total</td>";
echo "<td>$row->target</td>";
echo "<td>$row->present</td>";
echo "</tr>";
}
?>
逻辑如下((将"A/B"转换为浮点数)/"C")* 100.00)为"D%"所有的值必须是整数，当你除它们时，它必须转换为浮点数，这样计算才能正确进行。
