Unhappy Help please with "Random Selection"
I would like to pull a randomly selected entery out of a database & have tried the following command:

#!/usr/local/bin/php4

<?

$db_name = "******";
$table_name = "rand";

$connection = @mysql_connect ("****", "*****", "****")
or die("Couldn't connect.");

$db = @mysql_select_db($db_name, $connection)
or die("Couldn't select database.");


$sql = "SELECT *, RAND() AS r FROM rand ORDER BY r LIMIT 1;";
FROM $table_name
";

$result = @mysql_query($sql,$connection)
or die("Couldn't execute query.");

while ($row = mysql_fetch_array($result)) {
$id = $row[0];

echo "$id"
";

}

?>



Which only throws back an error message.

Any help please.

Send a message via ICQ to Onslaught
try this instead:
PHP Code:
 $sql = "SELECT * FROM $table_name ORDER BY rand() LIMIT 1";

Sorry onslaught I should have said, I'm using an older version of MySQL. I think the code you've given will only work on the newer versions.
