MySQL 5 - WHERE on 2 clauses

I'm trying to figure out the best means of doing a querry but i'm stumped on the right syntax.


Basically i have a Field "Status" that can be either 0, 1, or 2. Only one record can have a value of 2 at a time so if a admin edits a record and sets it to 2, then all other instances of stattus = 2 are set to 1

Does this look good for my query?
SET Status=1 WHERE ID <> '$ID' GROUP BY Status = 2

you don't need to group by anything. that is usually only for select statements. you can just say AND status=2

UPDATE Table SET Status=1 WHERE ID <> '$ID' AND Status = 2

thanks, i'll give it a try!

So here is my final code for this bit, see any flaws?

if ($Status == 2){$update = mysql_query("UPDATE ".$dtable." SET Status=1 WHERE ".$keyID." <> '$NewID' AND Status = 2")or die(mysql_error()); }
