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
