有没有人遇到过这个错误:一般错误:1390 Prepared statement contains too many placeholders
我刚刚通过 SequelPro 导入了超过 50,000 条记录,现在当我在视图中查看这些记录(Laravel 4)时,我得到一般错误:1390 Prepared statement contains too many placeholders。
我的 AdminNotesController.php 文件中的以下 index() 方法是生成查询和呈现视图的内容。
public function index()
{
$created_at_value = Input::get('created_at_value');
$note_types_value = Input::get('note_types_value');
$contact_names_value = Input::get('contact_names_value');
$user_names_value = Input::get('user_names_value');
$account_managers_value = Input::get('account_managers_value');
if (is_null($created_at_value)) $created_at_value = DB::table('notes')->lists('created_at');
if (is_null($note_types_value)) $note_types_value = DB::table('note_types')->lists('type');
if (is_null($contact_names_value)) $contact_names_value = DB::table('contacts')->select(DB::raw('CONCAT(first_name," ",last_name) as cname'))->lists('cname');
if (is_null($user_names_value)) $user_names_value = DB::table('users')->select(DB::raw('CONCAT(first_name," ",last_name) as uname'))->lists('uname');
// In the view, there is a dropdown box, that allows the user to select the amount of records to show per page. Retrieve that value or set a default.
$perPage = Input::get('perPage', 10);
// This code retrieves the order from the session that has been selected by the user by clicking on a table column title. The value is placed in the session via the getOrder() method and is used later in the Eloquent query and joins.
$order = Session::get('account.order', 'company_name.asc');
$order = explode('.', $order);
$notes_query = Note::leftJoin('note_types', 'note_types.id', '=', 'notes.note_type_id')
->leftJoin('users', 'users.id', '=', 'notes.user_id')
->leftJoin('contacts', 'contacts.id', '=', 'notes.contact_id')
->orderBy($order[0], $order[1])
->select(array('notes.*', DB::raw('notes.id as nid')));
if (!empty($created_at_value)) $notes_query = $notes_query->whereIn('notes.created_at', $created_at_value);
$notes = $notes_query->whereIn('note_types.type', $note_types_value)
->whereIn(DB::raw('CONCAT(contacts.first_name," ",contacts.last_name)'), $contact_names_value)
->whereIn(DB::raw('CONCAT(users.first_name," ",users.last_name)'), $user_names_value)
->paginate($perPage)->appends(array('created_at_value' => Input::get('created_at_value'), 'note_types_value' => Input::get('note_types_value'), 'contact_names_value' => Input::get('contact_names_value'), 'user_names_value' => Input::get('user_names_value')));
$notes_trash = Note::onlyTrashed()
->leftJoin('note_types', 'note_types.id', '=', 'notes.note_type_id')
->leftJoin('users', 'users.id', '=', 'notes.user_id')
->leftJoin('contacts', 'contacts.id', '=', 'notes.contact_id')
->orderBy($order[0], $order[1])
->select(array('notes.*', DB::raw('notes.id as nid')))
->get();
$this->layout->content = View::make('admin.notes.index', array(
'notes' => $notes,
'created_at' => DB::table('notes')->lists('created_at', 'created_at'),
'note_types' => DB::table('note_types')->lists('type', 'type'),
'contacts' => DB::table('contacts')->select(DB::raw('CONCAT(first_name," ",last_name) as cname'))->lists('cname', 'cname'),
'accounts' => Account::lists('company_name', 'company_name'),
'users' => DB::table('users')->select(DB::raw('CONCAT(first_name," ",last_name) as uname'))->lists('uname', 'uname'),
'notes_trash' => $notes_trash,
'perPage' => $perPage
));
}
任何意见,将不胜感激。谢谢。
