Here is what I would do, if I was doing what I think you're doing, which I'm not at all sure of... <?php $query = "select col1, col2, ... from table_name where 1 = 1 "; if (isset($value1)){ $query .= " and col1 = $value1 "; } if (isset($value2)){ $query .= " and col2 = $value2 "; } if (isset($value3)){ $query .= " and col3 = $value3 "; } mysql_query($query) or error_log(mysql_error()); ?> The where 1 = 1 technique is a sort of "yeast" to allow all the subsequent parts to start with " and ..." If you change to " OR ... " then you need " where 1 = 0 " Think about it or work through an example to see why :-) -- Like Music? http://l-i-e.com/artists.htm Off-Topic: What is the moral equivalent of 'cat' in Windows?
