Php Pdo - 选择最后插入

Question

i have a 'insert into' and 'select' querys together in one query.

$_SESSION['LoginUID']=1;
$Mesaj='ffdd';
$Ek=12;
$cid=112;
$Kaydet=$db->query("
               Insert Into Reply (Kimden,Mesaj,Ek,cid) 
               Values (".$_SESSION['LoginUID'].",'$Mesaj',$Ek,$cid);
               select r_id,KayitZaman from Reply 
               where r_id=LAST_INSERT_ID();")
            ->fetch(PDO::FETCH_ASSOC);

But i cant select last inserted row. It must return like this
<kbd>m_id  </kbd><kbd>KayitZaman       </kbd>
<kbd>16      </kbd><kbd>1413130807000</kbd>

How can i do that in one query? Or other way.

Answer 1

You cannot run two queries at the same time, only one at the time

After the insert, run the select:

$stmt = $db->query('select r_id,KayitZaman from Reply where r_id=LAST_INSERT_ID()');

or you can use the built in function to pass the last inserted Id

$stmt = $db->prepare('select r_id,KayitZaman from Reply where r_id= ?');
$stmt->execute(array($db->lastInsertId()));

If you want to do the whole thing at once then create a stored procedure.

EDIT:

DELIMITER //
 CREATE PROCEDURE sp_insert_get_reply(IN `p_Kimden`, 
                                      IN `p_Mesaj`, 
                                      IN `p_Ek`, 
                                      IN `p_cid`)
   BEGIN
   INSERT INTO `Reply` (`Kimden`, `Mesaj`, `Ek`, `cid`) 
   VALUES (p_Kimden, p_Mesaj, p_Ek, p_cid);

   SELECT `r_id`, `KayitZaman` 
   FROM Reply WHERE r_id=LAST_INSERT_ID()
   END //
 DELIMITER ;

then call the function from PDO:

$stmt = $db->prepare('CALL sp_insert_get_reply(?, ?, ?, ?)');
$stmt->execute(($_SESSION['LoginUID'], $Mesaj, $Ek, $cid));
