Voorbeeld: example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb");
$sql = <<<EOD
SELECT g.event_code, e.name
FROM game g
JOIN event e ON g.event_code=e.code
WHERE host_year = ? AND event_code NOT IN (SELECT event_code FROM game WHERE host_year=?) GROUP BY event_code;
EOD;
$req = cubrid_prepare($conn, $sql);
cubrid_bind($req, 1, 2004);
cubrid_bind($req, 2, 2000);
cubrid_execute($req);
$row_num = cubrid_num_rows($req);
printf("There are %d event that exits in 2004 olympic but not in 2000. For example:\n\n", $row_num);
printf("%-15s %s\n", "Event_code", "Event_name");
printf("----------------------------\n");
$row = cubrid_fetch_assoc($req);
printf("%-15d %s\n", $row["event_code"], $row["name"]);
$row = cubrid_fetch_assoc($req);
printf("%-15d %s\n", $row["event_code"], $row["name"]);
cubrid_disconnect($conn);
?>
