    例1 cubrid_rollback() example

    <?php
    $conn     = cubrid_connect("127.0.0.1", 33000, "demodb", "dba");
    cubrid_set_autocommit($conn,false);

    @    cubrid_execute($conn, "DROP TABLE publishers");

    $sql = <<<EOD
    CREATE TABLE publishers(
    pub_id CHAR(3),
    pub_name VARCHAR(20),
    city VARCHAR(15),
    state CHAR(2),
    country VARCHAR(15)
    )
    EOD;

    if (!    cubrid_execute($conn, $sql)) {
    printf("Error facility: %d\nError code: %d\nError msg: %s\n", cubrid_error_code_facility(), cubrid_error_code(), cubrid_error_msg());

    cubrid_disconnect($conn);
    exit;
    }

    $req = cubrid_prepare($conn, "INSERT INTO publishers VALUES(?, ?, ?, ?, ?)");

    $id_list = array("P01", "P02", "P03", "P04");
    $name_list = array("Abatis Publishers", "Core Dump Books", "Schadenfreude Press", "Tenterhooks Press");
    $city_list = array("New York", "San Francisco", "Hamburg", "Berkeley");
    $state_list = array("NY", "CA", NULL, "CA");
    $country_list = array("USA", "USA", "Germany", "USA");

    for (    $i = 0, $size = count($id_list); $i < $size; $i++) {
    cubrid_bind($req, 1, $id_list[$i]);
    cubrid_bind($req, 2, $name_list[$i]);
    cubrid_bind($req, 3, $city_list[$i]);
    cubrid_bind($req, 4, $state_list[$i]);
    cubrid_bind($req, 5, $country_list[$i]);

    if (!(    $ret = cubrid_execute($req))) {
    break;
    }
    }

    if (!    $ret) {
    cubrid_rollback($conn);
    } else {
    cubrid_commit($conn);

    $req = cubrid_execute($conn, "SELECT * FROM publishers");
    while (    $result = cubrid_fetch_assoc($req)) {
    printf("%-3s %-20s %-15s %-3s %-15s\n",
    $result["pub_id"], $result["pub_name"], $result["city"], $result["state"], $result["country"]);
    }
    }

    cubrid_disconnect($conn);
    ?>

    上の例の出力は以下となります。

    P01 Abatis Publishers    New York        NY  USA            
P02 Core Dump Books      San Francisco   CA  USA            
P03 Schadenfreude Press  Hamburg             Germany        
P04 Tenterhooks Press    Berkeley        CA  USA
