MySQL - 检查INSERT查询是否失败（即，$ sql存在），确保注册数据在数据库中正确？

Question

我们公司正在创建（非常活跃）注册表格。处理这些数据的应用程序是Laravel 5应用程序。我正试图消除注册处理脚本中的所有不必要的查询。但是请注意，它是甚至更​​重要我们正确记录每个注册。

现在，我写了这个到应用程序流：

$entry_timestamp = time(); 

DB::table('form_registration_data')->insert($userDataArray); 

$matchArray = array('last_name' => $last_name, 'entry_timestamp' => $entry_timestamp);// the (required field last_name/unix entry_timestamp) pair is (safely IMO) assumed to be a unique "ID" 

$sql = DB::table('form_registration_data')->select('entry_id')->where($matchArray)->first(); 

if (!empty($sql)) { 
    //from this point script knows user data was recorded properly 
} else { 
    $errorMsg = 'There was a problem with the server. Please try again."; 
} 

我之所以写了一个单独的选择查询我不是100％一定的，只是因为插入查询没有失败这个手段它正确执行和数据被正确地记录在DB（请记住，这是最重要的方面）

换句话说，这就是为什么我没有写这样的剧本：

$sql = DB::table('form_registration_data')->insert($userDataArray); 

if ($sql) { 
    //was the data truly recorded properly - 100% guaranteed ??? 
} else { 
    $errorMsg = 'There was a problem with the server. Please try again."; 
} 

我太过分了吗？换句话说，插入查询GUARANTEE的非失败是否在DB中记录了正确的数据？

这将工作。您还可以使用$数据 - > id来引用联接表作为外键插入：

// In your models file, this will set table. 
class Registration extends Model { 

    protected $FIELD1; 
    protected $FIELD2; 
    protected $FIELD3; 
    protected $FIELD4; 
    protected $FIELD5; 
    protected $FIELD6; 
    protected $FIELD7; 
} 


//In your controller: 

$data = new Registration(); 

$data->FIELD1 = VALUE1; 
$data->FIELD2 = VALUE2; 
$data->FIELD3 = VALUE3; 
$data->FIELD4 = VALUE4; 
$data->FIELD5 = VALUE5; 
$data->FIELD6 = VALUE6; 

if($data->save()) { 
    echo 'ID: ' & $data->id & ' Saved.' 
}
