> Anyone know why this is happening? I have mySQL on Win2000 Server with IIS

>
> mysql_num_rows(): supplied argument is not a valid MySQL result resource
>
> Here is my code:
>
> <?
>   $conn = mysql_connect('localhost', "xxx", "yyy") or die('Could not
connect
> to db');
>   $result = mysql_query('select * from blah');
>   echo "Number of rows: " . mysql_num_rows($result);
>   if (mysql_num_rows($result) > 0) {
>    while ($row = mysql_fetch_row($result)) {
>     for ($i = 0; $i < sizeOf($row); $i++) {
>      echo "$i: " . $row[$i] . "<BR>";
>     }
>    }
>   }
> ?>
>
> It couldn't get any simpler.  I just installed mySQL on my machine and am
> trying to see what I can do with it giving Win2K and IIS.
>
> AUGH! Thanx
