MySQL抛出错误但可以正常工作-PhpMyAdmin没有错误

Question

I am running this query on my MySQL Database - with mysql_query it throws me an error but the data is still properly inserted into the table. If I enter it in PhpMyAdmin it works without error.

INSERT INTO `kommentare` VALUES(NULL,'1','MyName','MyEmail','MyText','2014-08-05');

PHP :

$name = mysql_escape_string($name); 
$email = mysql_escape_string($email); 
$kommentar = mysql_escape_string($kommentar); 
$datum = mysql_escape_string($datum); 
$reiseid = str_replace("/", "", $reiseid); 
$query = "INSERT INTO kommentare VALUES(NULL,'" . $reiseid . "','" . $name . "','" . $email . "','" . $kommentar . "','" . $datum . "');";
$result = mysql_query($query) or die(mysql_error()); 
echo $query; 

Error:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1

How is that possible? I am experienced with MySQL but this wrecks my nerves - it works but says it doesn't?!

UPDATE:

It just happens when I have more than one entry in the table. ANd even if I remove all the ' it gives me the same error, saying I should check near the '

Answer 1

If the first column is a auto-increment primary key, you don't pass it NULL , you pass it DEFAULT :

INSERT INTO kommentare VALUES 
(DEFAULT,'$reiseid','$name','$email','$kommentar','$datum');

But really you should instead be naming your columns and skipping those that you don't have a value for:

INSERT INTO kommentare 
(reiseid, name, email, kommentar, datum)
VALUES
('$reiseid','$name','$email','$kommentar','$datum');

SOLUTION:

My id has been passed not as 1 but as 1/ for some reason. This caused MySQL to crash although it was not shown to me. I replace the / with "" now and everything works fine!
