我使用學說查詢生成器來篩選記錄，這是我認爲這是導致問題的一部分：主義LIKE帶俄語字符

$query = $query->where('i.offernumber LIKE :search') 
    ->orWhere('o.client LIKE :search') 
    ->orWhere('o.sticker LIKE :search') 
    ->orWhere('o.gu LIKE :search') 
    ->orWhere('o.project LIKE :search') 
    ->orWhere('o.quantity LIKE :search') 
    ->orWhere('o.date LIKE :search') 
    ->leftJoin('o.previous', 'p') 
    ->leftJoin('p.input', 'pi') 
    ->orWhere('pi.offernumber LIKE :search') 
    ->setParameter('search', "%".$search."%");

的問題是，我得到以下錯誤，當我輸入俄文字母人物：

An exception occurred while executing 'SELECT c0_.id AS id0, c0_.client AS client1, c0_.quantity AS quantity2, c0_.next AS next3, c0_.status AS status4, c0_.date AS date5, c0_.sticker AS sticker6, c0_.gu AS gu7, c0_.project AS project8, c0_.completed AS completed9, c0_.rversion AS rversion10, c0_.input_id AS input_id11, c0_.previous AS previous12, c0_.user_id AS user_id13 FROM crm_order c0_ LEFT JOIN crm_input c1_ ON c0_.input_id = c1_.id LEFT JOIN crm_order c2_ ON c0_.previous = c2_.id LEFT JOIN crm_input c3_ ON c2_.input_id = c3_.id WHERE c1_.offernumber LIKE ?

SQLSTATE[HY000]: General error: 1271 Illegal mix of collations for operation 'like'

什麼可能會造成這個錯誤，並且是有辦法解決這個問題？

編輯

圍繞推動代碼，並試圖各種組合之後，我精確定位錯誤的原因，它的這2條如下因素線：

->orWhere('o.quantity LIKE :search') 
->orWhere('o.date LIKE :search')

Apratently那些2個變量不是字符串（數字和日期的MySQL類型），並且上面的查詢嘗試爲「LIKE％string％」查找不是字符串類型的列它會導致錯誤。與此相同的問題post

對於這個問題，有什麼可能的解決方案，因爲我仍然需要搜索字符串，數字和日期？

你有沒有在config.yml設置字符集
