试试这个......
//Loop through all tables
set_time_limit(0);
$res = mysqli_query($db,"SHOW TABLES");
while ($row = mysqli_fetch_row($res)) {
$table = $row[0];
//Add created_at column if not exist, else alter the field
$response = mysqli_query($db,"DELETE FROM " . $table . " WHERE staff_id = xyz");
if ($response)
echo "Data deleted from " . $table;
}

你可以这样做。您已加入所有表格,如下所示。在这里,我只加入了给定的表格。在删除记录之前还要考虑外键约束。
DELETE t1, t2, t3, t4 FROM
staff as t1
INNER JOIN access as t2 on t1.staff_id = t2.staff_id
INNER JOIN training as t3 on t1.staff_id=t3.staff_id
INNER JOIN notifications as t4 on t1.staff_id=t4.staff_id
WHERE t1.staff_id=xyz;
除非尝试这样:
$tables = array("staff", "access", "training", "notifications");
foreach ($tables as $table) {
$query = "DELETE FROM $table WHERE staff_id=xyz";
mysqli_query($db, $query);
}
