Question

I try to load about 30.000 record to mysql select. than i get this warning.
and than i try to break them into smaller limit. Every 1000. but why i still get this warning?

this is my code :

function processDataDb()
{
    $rowIncrement = 1000;

    $query = "SELECT count( * ) as totalfield FROM `isc_xml_data` ";
    $result = mysql_query($query) or die ("$query" . mysql_error());

    if ($result) 
    {
        $row = mysql_fetch_assoc($result);
        $total_row = $row['totalfield'];

        for($i = 0; $i < $total_row ; $i+=$rowIncrement)
        {
            $sql_c = "SELECT * FROM isc_xml_data order by id LIMIT " . $i . " , " . ($i + $rowIncrement - 1);
            $res_c = mysql_query($sql_c) or die (mysql_error());

            while($row = mysql_fetch_object($res_c)) 
            {
                echo $row->id."\n";
                $this->insertAndUpdateProduct($row->xmldata);       
            }

            unset($res_c);
        }

    } else {
        echo "result is unavailable";
    }
}

Thanks for any help.

$sql_c = "SELECT * FROM isc_xml_data order by id LIMIT " .
    $i . " , " . ($i + $rowIncrement - 1);

The second argument to LIMIT is how many you want, not the upper bound; try just $rowIncrement.
