Your statement is saying: if 3 is greater than 2, delete all Your WHERE criteria should be based upon a specific field's contents, NOT its position in a data base -Original Message- From: Jan Grafström [mailto:[EMAIL PROTECTED]] Sent: Tuesday, August 28, 2001 11:51 AM To: [EMAIL PROTECTED] Subject: [PHP-DB] How to delete specific row in mysql table?

Regards Jan That's because the number 3 is greater than the number 2, so is always true, and does nothing to identify the row you want to delete You need to find something unique to identify row number 3 with, then modify your WHERE clause to idenfity the row using that unique column, such as 'delete from mytable where rowid = 3' This is an SQL question really - you should probably consult an SQL reference jason -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
