#26855 [Opn->Bgs]: UPDATE query unexplicable behavior

ID: 26855 Updated by: eru@php.net Reported By: superzouz at hotmail dot com -Status: Open +Status: Bogus Bug Type: MySQL related Operating System: various PHP Version: 4.3.4 New Comment: Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Thank you for your interest in PHP. You see the \' in the error message? That's why. See http://www.php.net/mysql_real_escape_string Previous Comments: ------------------------------------------------------------------------ [2004-01-09 13:44:53] superzouz at hotmail dot com Description: ------------ When I run the following query through PHP: UPDATE config_intranet SET confvalue = '192.168.0.1' WHERE confkey 'vpn_server_ip' I get the following error. 1064: You have an error in your SQL syntax near 'query' at line 1 But if I type the same query directly into MySQL, it is executed correctly! I was able to reproduce this situation on my PC (Windows XP SP1) with PHP 4.3.4 and MySQL "client api version 3.23.49", and on 2 internet hosting providers running PHP 4.x with mySql on *nix systems, so it is not an issue with my configuration. There is nothing in the official PHP docs stating that a query would be handled differently by PHP and MySQL. Thanks Reproduce code: --------------- $conn = mysql_connect ( "localhost", "rolfen" , "" ); mysql_select_db("dergham", $conn); $query = mysql_real_escape_string("UPDATE config_intranet SET confvalue = '192.168.0.1' WHERE confkey = 'vpn_server_ip'"); $res = mysql_query(query, $conn); if ($res) echo "success"; else { die("Error while updating config table. Error Output: <br/>". mysql_errno() . ": " . mysql_error(). "<br/>"."Query follows:<br/>".$query); return False; } ?> Expected result: ---------------- success Actual result: -------------- Content-type: text/html X-Powered-By: PHP/4.3.2 X-Powered-By: PHP/4.3.2 Content-type: text/html Error while updating config table. Error Output: <br/>1064: You have an error in your SQL syntax near 'query' at line 1<br/>Query follows:<br/>UPDATE config_intranet SET confvalue = \'192.168.0.1\' WHERE confkey = \'vpn_server_ip\' ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=26855&edit=1
