อยากทราบคำสั่ง ที่ใช้ในการนับจำนวน record ของ oracle อ่าค่ะ

<?
	$objConnect = oci_connect("myuser","mypassword","TCDB");
	$strSQL = "SELECT * FROM CUSTOMER ORDER BY CUSTOMERID ASC";
	$objParse = oci_parse ($objConnect, $strSQL);
	oci_execute ($objParse,OCI_DEFAULT);

	$Num_Rows = oci_fetch_all($objParse, $Result);
?>

<? 
    $objConnect = oci_connect("myuser","mypassword","TCDB"); 

    $strSQL = "SELECT * FROM CUSTOMER ORDER BY CUSTOMERID ASC"; 

    $objParse = oci_parse ($objConnect, $strSQL); 

    $Result = oci_execute ($objParse,OCI_DEFAULT); 

    $Num_Rows = oci_fetch_all($objParse, $Result); 
?>
