实例如下所示:
$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();
中午没睡觉一直调试,心塞…
错误写法
//错误写法 $data = Content::whereIn(\'id\',$ids) ->select(\'id\') ->orderByRaw(\"FIND_IN_SET(\'id\', \"\' . implode(\",\", $ids) . \'\"\' . \")\") ->get(); //该写法查询顺序是按照id大小正序排序
原因解析
//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
