MySQL - 檢查INSERT查詢是否失敗（即，$ sql存在），確保註冊數據在數據庫中正確？

Question

我們公司正在創建（非常活躍）註冊表格。處理這些數據的應用程序是Laravel 5應用程序。我正試圖消除註冊處理腳本中的所有不必要的查詢。但是請注意，它是甚至更​​重要我們正確記錄每個註冊。

現在，我寫了這個到應用程序流：

$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."; 
} 

我之所以寫了一個單獨的選擇查詢我不是100％一定的，只是因爲插入查詢沒有失敗這個手段它正確執行和數據被正確地記錄在DB（請記住，這是最重要的方面）

換句話說，這就是爲什麼我沒有寫這樣的劇本：

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

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

我太過分了嗎？換句話說，插入查詢GUARANTEE的非失敗是否在DB中記錄了正確的數據？

這將工作。您還可以使用$數據 - > id來引用聯接表作爲外鍵插入：

// 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.' 
}
