具有多个ID列和php的Mysql查询

SELECT * FROM table_name WHERE id1 = 'value1' AND id2 = 'value2';

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

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

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

$id1 = 'value1';
$id2 = 'value2';

// 构建查询语句
$sql = "SELECT * FROM table_name WHERE id1 = '$id1' AND id2 = '$id2'";
$result = $conn->query($sql);

// 检查查询结果
if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "ID1: " . $row["id1"]. " - ID2: " . $row["id2"]. "<br>";
    }
} else {
    echo "没有匹配的记录";
}

// 关闭连接
$conn->close();
?>
