RE: [PHP] newbie: mysql statement

If you could retrieve the max(posted) prior to doing the update you could; SELECT max(posted) from header WHERE parent = '$this->postid' and substitute the value in the following query; Update header SET parent='$this->parent' WHERE parent = '$this->postid' AND posted = $retrieved_posted A subselect would work great here by not in MySQL.

I tried the following mysql statement: "UPDATE header WHERE parent = '$this->postid' ORDER by posted SET parent='$this->parent' LIMIT1"; but apparently you can't use ORDER in an UPDATE statement. If I take order out, the statement works. That being true (and please correct me if its not) how can I ensure that the newest record is the one being acted upon?
