	      $stid = oci_parse($conn, $sql);

	      // The defines MUST be done before executing
	      oci_define_by_name($stid, 'LOCATION_ID', $locid);
	      oci_define_by_name($stid, 'CITY', $city);

	      oci_execute($stid);

	      while (oci_fetch($stid)) {
		  echo "Location id $locid is $city<br>
";
	      }

	      // Displays:
