Question

我在连接到sql DB的表中有多列输入DATE字段。现在我需要总结并显示每列的用户条目数。不应计算NULL值。

我可以计算行数。但不是参赛作品。请帮忙。 EX：如果我在一列中有10行，并且用户目前只输入了2个输入，那么输出应该在另一个表中显示为2。

这是我目前的完整代码：

    <?php
include_once('confiq.php');
$sql="SELECT * FROM fiberexcel";
$records=mysqli_query($conn, $sql);
?>

<?php
$page = $_SERVER['PHP_SELF'];
$sec = "10";
?>

<style type="text/css">

table {
    border-collapse: collapse;
    width: auto;
    overflow-y: scroll;
}


td{
    background-color: #fff;
    text-align: center;
}
</style>

Answer 1

如果您想count table中给定列的不同值的数量select sum(foo) from (select 1 as foo from fiberexcel group by givencolumn) t，您可以这样做：

fiberexcel.givencolumn

内部查询将为foo中的每个可能值创建一个组，并选择1作为sum。由于每个组1都与之相关，foo的{{1}}将产生您需要的值。您可以为任何列执行此操作。

编辑：

假设你有一个表T，你在这个表中有一个C列。如果您有兴趣根据不同的C值了解汇总信息，那么您需要进行分组：

select C
from T
group by C

此查询的结果将包含C上的T组。假设您对T中每个可能的C元素的数量感兴趣。在这种情况下，您需要进行计数：

select C, count(*) as element_number
from T
group by C

现在，在我们的例子中，我们有兴趣知道组的数量（不同值的数量），因此我们进行分组并为每个组选择1并添加它们。但如果它对你更容易理解/同情，那么它可以以不同的方式解决。例如：

select count(*)
from
(select givencolumn
 from fiberexcel
 group by givencolumn) t

Answer 2

<?php
//$i = 1;
while ($fiberexcel=mysqli_fetch_assoc($records)){
}
?>
<?php
$query = "SELECT COUNT(*) FROM fiberexcel";
$result = mysqli_query($conn,$query);
$TARGETS = mysqli_fetch_row($result);
?>

<!--Quotation11-->
        <tr>
        <td>Sent to Contractors for Quotation</td>
        <?php echo "<td>"  .$TARGETS[0] ." </td>";

        $query = "SELECT COUNT(*) FROM fiberexcel WHERE Quotation11 ";
        $result = mysqli_query($conn,$query);
        $ACTUALS = mysqli_fetch_row($result);
        echo "<td>" .$ACTUALS[0] . "</td>";

        $pers = ROUND($ACTUALS[0]/$TARGETS[0] *100 ) . "%";
        echo "<td>" .$pers . "</td>";
        ?>
        </tr>

<!--ApprovalJFSRequest13-->
        <tr><td>SO Approval for JFS Requested</td>
        <?php echo "<td>"  .$TARGETS[0] ." </td>";

        $query = "SELECT COUNT(*) FROM fiberexcel WHERE ApprovalJFSRequest13 ";
        $result = mysqli_query($conn,$query);
        $ACTUALS = mysqli_fetch_row($result);
        echo "<td>" . $ACTUALS[0] . "</td>" ;

        $pers = ($ACTUALS[0]/$TARGETS[0]) *100 . "%";
        echo "<td>" .$pers . "</td>";
        ?>
        </tr>

如何计算除null之外的每列中用户输入数据的数量？
