Sqlite 建立觸發器（刪除）
今天在移動裝置上需要做乙個刪除功能，兩個表itembase和itemsd，其中，itembase的id欄位和itemsd的sdpid欄位是一對一關係，現在要求刪除一條itembase的同時也刪除對應的itemsd，於是就想到了使用觸發器，寫法如下 create trigger itembase de...
觸發器詳解 （一）D觸發器
觸發器是時序邏輯電路的基本單元，用來儲存1位2進製資訊，具有記憶和儲存功能，其資訊由雙穩態電路來儲存。觸發器位脈衝邊緣敏感器間，分為上公升沿敏感和下降沿敏感。觸發器的種類很多，由d觸發器，j k觸發器，t觸發器等。並且根據運用場景的不同，觸發器還會有置位，復位，使能和選擇等功能。d觸發器是一種最簡單...
