mysql动态表明名取数

SET @tablename = 'users_2023';

SELECT * FROM @tablename WHERE id = 1;

<?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 用户输入的表名
$tableName = $_GET['table'];

// 预处理语句
$stmt = $conn->prepare("SELECT * FROM ? WHERE id = ?");
$stmt->bind_param("si", $tableName, $id);

// 绑定参数并执行
$id = 1;
$stmt->execute();

$result = $stmt->get_result();
while ($row = $result->fetch_assoc()) {
    echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
}

$stmt->close();
$conn->close();
?>
