Question

如何返回我在同一查询中创建的记录。

我尝试了$row[Password]，但它不起作用。请帮忙

$sql = "SELECT COUNT(*) FROM characters WHERE GUID=:GUID";
$stmt = $pdo->prepare($sql);
$stmt->bindParam(':GUID', $_GET['GUID'], PDO::PARAM_INT);
    $stmt->bindColumn(4, $charactername);
$stmt->execute();
$res = $stmt->fetchColumn();
if($res == 1) {
    echo "Already created";
}


if(!$res){
        $sql = "INSERT INTO characters (GUID,Charactername,Password) VALUES (:GUID,:Charactername,FLOOR( 1000 + ( RAND( ) *8999 ) ))";
        $stmt= $pdo->prepare($sql);
        $stmt->bindParam(':GUID', $_GET['GUID'], PDO::PARAM_INT);
        $stmt->bindParam(':Charactername', $_GET['Charactername'], PDO::PARAM_INT);                 
        $stmt->execute();
        echo " THIS password created with FLOOR";
}

Answer 1

使用private void sMovieSkipSlider_MouseLeftButtonUp(object sender, MouseButtonEventArgs e) { if (TotalTime.TotalSeconds > 0) { CurrentMediaPlayer.MediaElement.Position = TimeSpan.FromSeconds(sMovieSkipSlider.Value * TotalTime.TotalSeconds); } }之后的DataContext获取插入的记录ID，然后进行另一次查询以选择记录。

Answer 2

您可以在执行后通过$id = $stmt->lastInsertId();返回最后插入的ID，然后对返回的ID执行select。

Answer 3

如果您需要获取随机生成的密码，可以使用多个查询：

// vue/types/vue.d.ts
export interface VueConstructor<V extends Vue = Vue> {
    set<T>(object: object, key: string, value: T): T;
    set<T>(array: T[], key: number, value: T): T;
}

如果您希望从上一个语句中插入所有值，也可以使用LAST_INSERT_ID（）：

<?php

$_GET['GUID'] = 1;
$_GET['Charactername'] = 'test';
$sql = "SET @password := FLOOR( 1000 + ( RAND( ) *8999 ));
        INSERT INTO characters (GUID,Charactername,Password) VALUES (:GUID,:Charactername,@password);
        SELECT @password as Password";

$stmt= $pdo->prepare($sql);
$stmt->bindParam(':GUID', $_GET['GUID'], PDO::PARAM_INT);
$stmt->bindParam(':Charactername', $_GET['Charactername'], PDO::PARAM_STR);                 
if ($stmt->execute()) {
    do {
        if ($rowset = $stmt->fetch(PDO::FETCH_ASSOC)) {
            echo " THIS password created with FLOOR: " . $rowset['Password'];
        }
    } while ($stmt->nextRowset());
}
