Вставка нескольких записей в MySQL Использование MySQLi и PDO
Несколько операторов SQL должны быть выполнены с mysqli_multi_query() функции.
Следующие примеры добавить три новые записи в "MyGuests" таблицу:
Пример (MySQLi Object-oriented)
<?php
$servername = "localhost";
$username = "username";
$password =
"password";
$dbname =
"myDB";
// Create connection
$conn =
new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";
$sql .= "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]');";
$sql .= "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";
if ($conn->multi_query($sql) === TRUE) {
echo "New
records created successfully";
} else {
echo
"Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
?>
Обратите внимание, что каждый SQL оператор должен быть разделен точкой с запятой.
Пример (MySQLi Procedural)
<?php
$servername = "localhost";
$username = "username";
$password =
"password";
$dbname =
"myDB";
// Create connection
$conn = mysqli_connect($servername, $username, $password,
$dbname);
// Check connection
if (!$conn) {
die("Connection
failed: " . mysqli_connect_error());
}
$sql = "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]');";
$sql .= "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]');";
$sql .= "INSERT INTO
MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')";
if (mysqli_multi_query($conn, $sql)) {
echo "New
records
created successfully";
} else {
echo "Error: "
. $sql . "<br>" . mysqli_error($conn);
}
mysqli_close($conn);
?>
Путь PDO немного отличается:
Пример (PDO)
<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname =
"myDBPDO";
try {
$conn = new PDO("mysql:host=$servername;dbname=$dbname",
$username, $password);
// set the PDO error mode to exception
$conn->setAttribute(PDO::ATTR_ERRMODE,
PDO::ERRMODE_EXCEPTION);
// begin the transaction
$conn->beginTransaction();
// our SQL statements
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', '[email protected]')");
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Mary', 'Moe', '[email protected]')");
$conn->exec("INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('Julie', 'Dooley', '[email protected]')");
// commit the transaction
$conn->commit();
echo "New records created successfully";
}
catch(PDOException $e)
{
// roll back the transaction if something failed
$conn->rollback();
echo "Error: " . $e->getMessage();
}
$conn = null;
?>
