I have theese two queries : select count(*) as online from online where uid=''; select count(*) as online from online where uid!=''; Each online user has a uid (UserID), so if their logged inn this field will represent their unique uid. If not logged in its set to nothing. To detect how many online users the first query tells me all the "anonymous" users and the second gives "members". Since theese two queries are fired on every page hit, I would assume that if I could join theese queries into one I would atleast save the mysql for a 50% of the queries. Ive veeb experimenting on the count(expression) without any luck, probably since the server is running v4.0.17-standard So I wonder - is there any way I could join the above queries into one single query? Ofcourse I could easily add another field for the database, something like temp which is NULL for anonymous and 1 for user if this makes is easier to group the the query in some wmart way I havnt figured out at the moment. -- -- Kim Steinhaug ---------------------------------------------------------------------- There are 10 types of people when it comes to binary numbers: those who understand them, and those who don't. ---------------------------------------------------------------------- www.steinhaug.com - www.easywebshop.no - www.webkitpro.com ---------------------------------------------------------------------- -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
