[SOLVED] why sql error

[Sanjib Sinha]

Here is my code:

<?php

$c = mysql_connect('localhost','root',"");
$c = mysql_select_db('user', $c);
for($i=1; $i<=5; $i++){
$sql = "INSERT INTO 'users' ('username') VALUES('$i')";
$res = mysql_query($sql) or die(mysql_error());
echo "Row $i has been added <br>\n" ;

}

?>

 

Here is the output:

 

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 ''users' ('username') VALUES('1')' at line 1

 

 

Where is the problem?

' are used in mysql to contain strings ` are used to contain field names (or at least that is my belief)  try this

$sql = "INSERT INTO `users` (`username`) VALUES('$i')";

$sql = "INSERT INTO 'users' ('username') VALUES('$i')";

 

you put single slash around users take them away or use `` button under esc.

Hi Scott

Your belief is true. I removed ' and replaced with ` and it solved. Thank you. I have learnt a new thing.
