$ids = [5,7,3,1,2];$data = Content::whereIn('id',$ids) ->select('id') ->get();//查询结果是想按照wherein的顺序排序//正确写法$data = Content::whereIn('id',$ids) ->select('id')// ->orderBy(\DB::raw('FIND_IN_SET(id, "' . implode(",", $ids) . '"' . ")"))// ->orderBy(DB::raw("FIND_IN_SET(id, '" . implode(',', $ids) . "'" . ')'))// ->orderByRaw("FIND_IN_SET(id, '" . implode(',', $ids) . "'" . ')') ->orderBy(\DB::raw('FIND_IN_SET(id, "' . implode(",", $ids) . '"' . ")")) ->get(); |

//正确写法的sql语句为select `id` from `contents`order by FIND_IN_SET(id, "5,6,7,4,2,1") asc//错误写法的sql语句为select `id` from `contents`order by 'FIND_IN_SET(id, "5,6,7,4,2,1")' asc//或者select `id` from `contents`order by `FIND_IN_SET(id, "5,6,7,4,2,1")` asc //FIND_IN_SET()方法外面不要添加任何符号 |
以上这篇laravel 模型查询按照whereIn排序的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
