实例如下所示：
代码语言：javascript复制$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
代码语言：javascript复制//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
代码语言：javascript复制//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。
