使用Laravel查询构建器获取整数数组

Question

我有这个问题:

$inError = DB::table('errors')            
        ->select('fk_fact')
        ->distinct()
        ->get();

我希望它返回一个整数数组而不是返回一个对象数组,我不想循环遍历所有结果并逐个推送值...有没有办法用Laravel做到这一点？

Answer 1

当然,您可以使用内置lists()方法:

$inError = DB::table('errors')            
    ->select('fk_fact')
    ->distinct()
    ->lists('fk_fact');

您可能需要->all()在列表调用后添加.

这是我碰巧遇到的数据库中的一个修补程序示例:

>>> DB::table('teams')->select('name')->distinct()->lists('name');
=> [

     "Liverpool",
     "Manchester City",
     "Manchester United",
     "Newcastle United",
     "Norwich City",
     "Southampton",
     "Stoke City",
     "Sunderland",
     "Swansea City",
     "Tottenham Hotspur",
     "Watford",
     "West Bromwich Albion",
     "West Ham United",
