Question

I have a MySQL table called “privatemessage” with a primary key field called “messageid.”

I would like to have a PHP query that deletes any row from “privatemessage” where “messageid = $messageid.”

What sort of query does this?

Thanks in advance,

John

Answer 1

DELETE FROM `privatemessage` WHERE `messageid` = $messageid

That’s just the raw SQL query. Things like validating and escaping user input should certainly be considered.

For example, given messageid as an AUTO_INCREMENT integer primary key I’d simply run this in PHP (converting $messageid to an int using intval()):

mysql_query('DELETE FROM `privatemessage` WHERE `messageid` = ' . intval($messageid));
