在带有数组的 IN 语句之后的 WHERE 语句中使用更多占位符

如何解决在带有数组的 IN 语句之后的 WHERE 语句中使用更多占位符

我需要向以下查询添加更多占位符。这可能吗？我不知道从哪里开始，我在互联网上找不到任何选项。

现在的查询：

$in2  = str_repeat('?,',count($arrayid) - 1) . '?';
$sql2 = "SELECT COUNT(id) AS totalacc FROM account WHERE id IN ($in2) ";
$stmt2  = $MysqLi->prepare($sql2);
$types2 = str_repeat('i',count($arrayid));
$stmt2->bind_param($types2,...$arrayid);
$stmt2->execute();
$stmt2->bind_result($row['totalacc']);
    while($stmt2->fetch()) $totalacc = $row['totalacc']; 

我的目标查询：

$countname1 = '(Hallo)';
    $countname = trim(filter_var("%{$countname1}%",FILTER_SANITIZE_STRING));
$in2  = str_repeat('?,count($arrayid) - 1) . '?';
$sql2 = "SELECT COUNT(id) AS totalacc FROM account WHERE id IN ($in2) AND name LIKE ?";
$stmt2  = $MysqLi->prepare($sql2);
$types2 = str_repeat('i',s,...$arrayid,$countname); // Will never work,but how to do this? 
$stmt2->execute();
$stmt2->bind_result($row['totalacc']);
    while($stmt2->fetch()) $totalacc = $row['totalacc']; 

解决方法

您只需要将额外的值附加到您的参数数组和类型字符串中。这应该有效（未经测试）：

ArrayList<Birthday>

,

最简单的解决方案是使用 PDO 而不是 mysqli。这会容易得多。

如果您坚持使用 mysqli，那么您可以通过简单地忽略类型并将结果附加到数组来实现类似的目的。

$countname1 = '(Hallo)';
$countname = "%{$countname1}%";
$in2 = str_repeat('?,',count($arrayid) - 1) . '?';
$sql2 = "SELECT COUNT(id) AS totalacc FROM account WHERE id IN ($in2) AND name LIKE ?";
$stmt2 = $mysqli->prepare($sql2);

$arrayid[] = $countname;
$stmt2->bind_param(str_repeat('s',count($arrayid)),...$arrayid);
$stmt2->execute();
$stmt2->bind_result($totalacc);
$stmt2->fetch();

您甚至可以编写一个函数来从所有这些代码中抽象出来。
