Question

我正在使用MySQL（5.1.67）开发运动管理器应用程序的服务器端部分，InnoDB作为存储引擎，PHP（5.3.3）。

当我尝试在包含先前插入的行的多个表上执行包含任何类型查询的脚本时，这些行会自动消失。请注意，不会执行DELETE查询。

表users的示例：

我通过调用 add_user.php 脚本将行插入users：

<?php

function addUser($link, $username, $password, $email, $country, $president_id, $virtual)
{
    $response = array();

    $stmt = mysqli_stmt_init($link);
    if ($stmt = mysqli_prepare($link, "INSERT INTO users(username, password, email, country, president_id, virtual) VALUES(?, ?, ?, ?, ?, ?)"))
    {
        mysqli_stmt_bind_param($stmt, "ssssii", $username, $password, $email, $country, $president_id, $virtual);

        $result = mysqli_stmt_execute($stmt);

        if($result)
        {
            $response["success"] = 1;
            $response["message"] = "User successfully created";
            $response["id"] = mysqli_insert_id($link);

            echo json_encode($response);
        }
        else
        {
            $response["success"] = 0;
            $response["message"] = "Failed to create user";

            echo json_encode($response);
        }

        mysqli_stmt_store_result($stmt);

        mysqli_stmt_close($stmt);
    }
}


require_once __DIR__ . '/db_config.php';

$link = mysqli_connect(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);


mysqli_report(MYSQLI_REPORT_ALL);

if (isset($_POST['username']) && isset($_POST['password']) && isset($_POST['email']) && isset($_POST['country']) && isset($_POST['president_id']) && isset($_POST['virtual']))
{
    $username = $_POST['username'];
    $password = $_POST['password'];
    $email = $_POST['email'];
    $country = $_POST['country'];
    $president_id = $_POST['president_id'];
    $virtual = $_POST['virtual'];

    addUser($link, $username, $password, $email, $country, $president_id, $virtual);
}
else
{
    $response['script'] = "add_user";
    $response["success"] = 0;
    $response["message"] = "Required field(s) missing";

    echo json_encode($response);
}


mysqli_close($link);

?>

然后我通过调用 start_season.php 脚本在users上执行一些查询（在下面的代码中我执行了一个通用INSERT查询，因为生成的行为是相同）：

<?php

require_once "./add_user.php";
require_once "./add_club.php";
require_once "./add_president.php";
require_once "./add_coach.php";
require_once "./add_stadium.php";
require_once "./compete.php";
require_once "./generate_fixtures.php";
require_once "./remove_manager.php";


require_once __DIR__ . '/db_config.php';

$link = mysqli_connect(DB_SERVER, DB_USER, DB_PASSWORD, DB_DATABASE);


mysqli_query($link, "SELECT * FROM users WHERE username LIKE 'user%'");


mysqli_close($link);

?>

就像users中的所有先前行都消失了一样。我在这里缺少什么？

以前插入的行在调用PHP脚本时消失
