All ready read that and its clear as mud. It tells you update is different but gives no example.
I asked in my post what should I code for checking the result of a update. -----Original Message----- From: Logan, David (SST - Adelaide) [mailto:[EMAIL PROTECTED] Sent: Sunday, March 12, 2006 4:50 PM To: [EMAIL PROTECTED]; Mysql Subject: RE: Checking for good update Perhaps reading the manual would be a good start at http://us3.php.net/manual/en/function.mysql-num-rows.php It clearly states Retrieves the number of rows from a result set. This command is only valid for SELECT statements. To retrieve the number of rows affected by a INSERT, UPDATE, or DELETE query, use mysql_affected_rows(). You are using a function not valid for an UPDATE Regards --------------------------------------------------------------- ********** _/ ********** David Logan ******* _/ ******* ITO Delivery Specialist - Database ***** _/ ***** Hewlett-Packard Australia Ltd **** _/_/_/ _/_/_/ **** E-Mail: [EMAIL PROTECTED] **** _/ _/ _/ _/ **** Desk: +618 8408 4273 **** _/ _/ _/_/_/ **** Mobile: 0417 268 665 ***** _/ ****** ****** _/ ******** Postal: 148 Frome Street, ******** _/ ********** Adelaide SA 5001 Australia i n v e n t --------------------------------------------------------------- -----Original Message----- From: fbsd_user [mailto:[EMAIL PROTECTED] Sent: Monday, 13 March 2006 8:00 AM To: Mysql Subject: Checking for good update Using this code I get this error message.
