"read" is a reserved word in mysql (http://dev.mysql.com/doc/refman/5.0/en/reserved-words.html). You have to double-quote reserved words: mysql_query("SELECT * FROM mailbox WHERE \"read\"=''"); Graham Cossey wrote:

    could you please tell me what is the problem with this query
mysql_query("SELECT * FROM mailbox WHERE read=''"); i always get this warning: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in index.php on line 24 [/snip] THere is no apparent problem with the query, but there is a problem with mysql_num_rows(). Can you show us he code there?
I would hazard a guess that mysql_num_rows() is not being passed the correct query result handle as a parameter. ie: $result = mysql_query(...);
    $rows = mysql_num_rows($result);
