我想将4个查询的结果显示在一个单独的html表中（SQL Server 2012，PHP，HTML）。我已经可以显示一个数据库表的结果，但是一旦我开始查询其他3个表，它只返回第一个表中的一行。
以下代码只有一个查询并且工作正常 - 它显示有关患者的几个信息（姓名，站，房间，导管，个人ID，导管插入日期......），目前有三个不同的患者在表中，因此html表显示3行：
<?php
require_once('header.php');
$today = date("d.m.y");
$yesterday = date("d.m.y", time() - 60 * 60 * 24);
$dbyesterday = date("d.m.y", time() - 2*(60 * 60 * 24));
?>

<?php
require_once('server.php');
// DB-Query für die Visitenliste
$sql = "SELECT dbo.patients.Patientennummer, Vorname, Nachname, Station, Zimmer, Katheterart, Anlagedatum FROM dbo.patients INNER JOIN dbo.cathinsert ON dbo.patients.Patientennummer = dbo.cathinsert.Patientennummer ORDER BY Station ASC, Zimmer ASC";
$visdbyes = "SELECT (SELECT VisiteKind FROM dbo.visits WHERE VisiteDate = '$dbyesterday') AS VisiteKind";
$visyes = "SELECT (SELECT VisiteKind FROM dbo.visits WHERE VisiteDate = '$yesterday') AS VisiteKind";
$vistod = "SELECT (SELECT VisiteKind FROM dbo.visits WHERE VisiteDate = '$today') AS VisiteKind";
$result = sqlsrv_query($connection, $sql);
$result_vdy = sqlsrv_query($connection, $visdbyes);
$result_vy = sqlsrv_query($connection, $visyes);
$result_vt = sqlsrv_query($connection, $vistod);
$data = array();
while($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)){$data['row'] = $row;}
while($row = sqlsrv_fetch_array($result_vdy, SQLSRV_FETCH_ASSOC)) {$data['dby'] = $row;}

结果，我有一个包含3行的表格以及我需要的所有信息。 但是一旦我开始添加更多查询，附加信息就会正确显示，但仅适用于第一行！它是唯一显示的行。我真的无法弄明白，为什么会这样。 这是不起作用的代码（所有信息都显示正确，甚至是来自其他查询的信息，但只有一行 - >只有第一名患者，尽管有3名保存在数据库中，尽管第一个代码显示所有3名患者以正确的方式）：

我跳你可以帮忙！ 提前谢谢，

我认为您应该每天使用一个查询，然后在while循环中检查日期。您还可以减少VisiteKind＆＃39; $ data数组中的字段：
$visd = "SELECT VisiteKind FROM dbo.visits";
$result_v = sqlsrv_query($connection, $visd);
$data = ['dby'=> [], 'yes'=> [], 'tod'=> []];
while($row = sqlsrv_fetch_array($result_v, SQLSRV_FETCH_ASSOC)) {
switch($row['VisiteKind']){
case $dbyesterday:
array_push($data['dby'],$row['VisiteKind']);
break;
case $yesterday:
array_push($data['yes'],$row['VisiteKind']);
break;
case $today:
array_push($data['tod'],$row['VisiteKind']);
break;
}
}
