我不明白为什么会出现此错误:

Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource

我的代码是:

$alreadyMember = mysql_fetch_assoc(mysql_query("SELECT id FROM members WHERE emailAddress='{$_SESSION['register']['email']}'"));

我这里也有错误:

$alreadyRegistered = mysql_fetch_assoc(mysql_query("SELECT confirm_code FROM memberstemp WHERE emailAddress='{$_SESSION['register']['email']}'"));
