MySQL是一種廣泛使用的關系型數據庫管理系統，很多人都想掌握這個技能。下面是一份MySQL教學腳本，將幫助你入門。

// 連接數據庫
$servername = "localhost";
$username = "username";
$password = "password";
// 創建連接
$conn = new mysqli($servername, $username, $password);
// 檢查連接是否成功
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
echo "連接成功";
// 創建數據庫
$sql = "CREATE DATABASE myDB";
if ($conn->query($sql) === TRUE) {
echo "數據庫創建成功";
} else {
echo "Error creating database: " . $conn->error;
}
// 創建表
$sql = "CREATE TABLE MyGuests (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
firstname VARCHAR(30) NOT NULL,
lastname VARCHAR(30) NOT NULL,
email VARCHAR(50),
reg_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)";
if ($conn->query($sql) === TRUE) {
echo "Table MyGuests created successfully";
} else {
echo "Error creating table: " . $conn->error;
}
// 添加數據
$sql = "INSERT INTO MyGuests (firstname, lastname, email)
VALUES ('John', 'Doe', 'john@example.com')";
if ($conn->query($sql) === TRUE) {
$last_id = $conn->insert_id;
echo "新記錄插入成功，ID為： " . $last_id;
} else {
echo "Error: " . $sql . "
" . $conn->error;
}
// 查詢數據
$sql = "SELECT id, firstname, lastname FROM MyGuests";
$result = $conn->query($sql);
if ($result->num_rows >0) {
// 輸出數據
while($row = $result->fetch_assoc()) {
echo "id: " . $row["id"]. " - Name: " . $row["firstname"]. " " . $row["lastname"]. "
";
}
} else {
echo "0 結果";
}
// 關閉連接
$conn->close();

通過學習以上腳本，你將學到如何創建數據庫、創建表、添加數據和查詢數據等基本操作。希望這份MySQL教學腳本能夠幫助到你入門學習。
