Hi, I'm getting an unknown colum `num` in where clause error with this query: $options = mysql_query("select options.*, count(option_items.optionID) as `num` from options left join option_links using (optionID) left join option_items on options.optionID = option_items.optionID where option_links.productID = '$productID' and `num` > 0"); But I'm defining it with the agregate function in the second line.. Any idea why it's popping the error? -Micah -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
