$where['class_id'] = ['in', '$cid_all']; $where['id'] = ['in', $all_user_id];//或這樣子 $where['title'] = ['like', '%php%']; $where['id'] = ['<>', $id]; $where['id'] = ['notin', $all_user_id];//不等於 //值爲數字 $id=419; $where[] = ['exp',Db::raw("FIND_IN_SET($id,category)")];//category值爲數字,例子:419,415,414 //值爲字符串 $id值等於dfd 要注意'引號 $where[] = ['exp',Db::raw("FIND_IN_SET('$id',category)")];//category值爲數字,例子:'349/417/419','349/413/415','349/413/416'
Db::name('menu')->where('FIND_IN_SET(:id,pid_all)',['id' => $id])->update([$field => $title]);
type 字段在數據庫是以 1,2,3 形式存在 已說到FIND_IN_SET函數的使用html
對於一些實在複雜的查詢,好比find_in_set,也能夠直接使用原生SQL語句進行查詢,例如:數據庫
Db::table('think_user') ->where('find_in_set(1,sids)') ->select();
爲了安全起見,咱們能夠對字符串查詢條件使用參數綁定,例如:安全
Db::table('think_user') ->where('find_in_set(:id,sids)',['id'=>$id]) ->select();
