带有MySql PDO的while循环内的while循环

Question

我需要知道如何进行此查询，因为现在只显示每天的第一个值，而不是每天的全部值。

我需要第二个查询，同时显示当天的所有用户，依此类推

这里是我的查询：

//First While:
<?php
$sql = $conn->prepare("SELECT count(id) AS total, fTera, DATE_FORMAT(fTera, '%d') AS day, DATE_FORMAT(fTera, '%d %M %Y') AS date
FROM TERA WHERE MONTH(fTera) = MONTH(current_date) AND YEAR(fTera) = YEAR(current_date) AND active != 0
GROUP BY date ASC");
$sql->execute();
while($row = $sql->fetch(PDO::FETCH_ASSOC)){
    $fT = $row['fTera'];
    $paci = $row['total'];
        
?>
//Second While
    <?php
    $tera = $conn->prepare("SELECT *
    FROM TERA WHERE fTera = :fecha AND active != 0");
    $tera->bindParam(':fecha', $fT, PDO::PARAM_STR);
    $tera->execute();
    $tPaci = 0;
    while($row1 = $tera->fetch(PDO::FETCH_ASSOC)){
        if($paci != $tPaci):
    ?>
    <tr>
        <td class="center"><?php echo $row1['nombre']; ?></td>
    </tr>
    <?php
        endif;
        $tPaci++; 
        } 
    ?>
//End Second While

<?php } ?>

//End First While

Answer 1

我已经做到了

我更改了这个 WHERE 子句：

WHERE fTera = :fecha

到这个：

fTera >= '$fT' AND fTera < '$fT' + INTERVAL 1 DAY

现在的第二个查询是：

$tera = $conn->prepare("SELECT *
FROM TERA WHERE fTera >= '$fT' AND fTera < '$fT' + INTERVAL 1 DAY AND active != 0");
$tera->execute();
....
