problem with select count(*)

[Ben]

Hi,

I have a problem with this query:
$link = mysql_connect(" localhost", "root", "pw");
$dbsel = mysql_select_db ('mydb', $link);
$lol='bibi';

$sql = "select count(*) as totuur from studres where where dag>= curdate()
AND logon='" . $lol . "'";
$result = mysql_query($sq l);
$row = mysql_fetch_fie ld($result,0);
// J'ai essayé avec: $row = mysql_fetch_row ($result);
$totu=$row[0];
The error is on line: $row = mysql_fetch_fie ld($result,0):
Warning: mysql_fetch_fie ld(): supplied argument is not a valid MySQL result
resource in c:\Inetpub\wwwr oot\myfile.php on line 74
Thanks
Ben

You have WHERE twice in "...from studres where where dag...", try what
happens if you remove the extra where. This is one of the reasons why sql
keywords should be written in CAPITAL letters. It's easier to spot the error
if you write:
"SELECT COUNT(*) AS totuur FROM studres WHERE WHERE dag>= CURDATE() AND
logon='$lol'"

And if you would have checked the result of the mysql_query() call, you
would have found your problem.

$result = mysql_query($sq l);
if ($result) {
$row = mysql_fetch_fie ld($result,0);
// J'ai essayé avec: $row = mysql_fetch_row ($result);
$totu=$row[0];
}
else
echo "MySQL error: " . mysql_error();
