使用 MySQLi 和 PDO 向 MySQL 插入多條數(shù)據(jù)


mysqli_multi_query() 函數(shù)可用來執(zhí)行多條SQL語(yǔ)句。


以下實(shí)例向 "MyGuests" 表添加了三條新的記錄:


實(shí)例 (MySQLi - 面向?qū)ο?


<?php$servername = "localhost";$username = "username";$password = "password";$dbname = "myDB"; // 創(chuàng)建鏈接$conn = new mysqli($servername, $username, $password, $dbname);// 檢查鏈接if ($conn->connect_error) { die("連接失敗: " . $conn->connect_error);} $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com');";$sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Mary', 'Moe', 'mary@example.com');";$sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Julie', 'Dooley', 'julie@example.com')"; if ($conn->multi_query($sql) === TRUE) { echo "新記錄插入成功";} else { echo "Error: " . $sql . "<br>" . $conn->error;} $conn->close();?>



實(shí)例 (MySQLi - 面向過程)


<?php$servername = "localhost";$username = "username";$password = "password";$dbname = "myDB"; // 創(chuàng)建鏈接$conn = mysqli_connect($servername, $username, $password, $dbname);// 檢查鏈接if (!$conn) { die("連接失敗: " . mysqli_connect_error());} $sql = "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com');";$sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Mary', 'Moe', 'mary@example.com');";$sql .= "INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Julie', 'Dooley', 'julie@example.com')"; if (mysqli_multi_query($conn, $sql)) { echo "新記錄插入成功";} else { echo "Error: " . $sql . "<br>" . mysqli_error($conn);} mysqli_close($conn);?>


實(shí)例 (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); // 開始事務(wù) $conn->beginTransaction(); // SQL 語(yǔ)句 $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) VALUES ('John', 'Doe', 'john@example.com')"); $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Mary', 'Moe', 'mary@example.com')"); $conn->exec("INSERT INTO MyGuests (firstname, lastname, email) VALUES ('Julie', 'Dooley', 'julie@example.com')"); // 提交事務(wù) $conn->commit(); echo "新記錄插入成功";}catch(PDOException $e){ // 如果執(zhí)行失敗回滾 $conn->rollback(); echo $sql . "<br>" . $e->getMessage();} $conn = null;?>
