Answer 1

@Abhshek's Answer is right and works for you but you can also try the following code if the id is not increment

DELETE FROM MARKS WHERE ID=(SELECT MAX(id) FROM MARKS)

Answer 2

This is not the best but a different solution.

DELETE FROM marks 
WHERE  id = (SELECT id 
             FROM   marks 
             ORDER  BY id DESC 
             LIMIT  1); 

Answer 3

Try this:

 $check = $db->prepare("SELECT `file` FROM `marks` WHERE `id` = ?");
    $check->execute(array($id));
    while ($checks=$check->fetchObject()) {
        $unlink = unlink($uploadDir.$checks->file);
    }

Where:

• uploadDir is your directory;

• $checks->file is your file name, saved in database;

• $id is the ID row you want to delete the file;

Answer 4

If id is auto-increment then you can use the following

delete from marks
order by id desc limit 1
