Question

我是使用laravel的新手，并且出现了这样的错误：

Call to undefined method Illuminate\Database\Query\Builder::toArray()

这是laravel中的查询生成器

$statsMoneyInPlay = DB::table('enginepoker_log.poker')
                    ->selectRaw("SELECT UNIX_TIMESTAMP(Date(ts)*100 as ts)")
                    ->selectRaw("sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay")
                    ->groupBy("Date(ts)")
                    ->orderBy("Date(ts)")
                    ->toArray();

Answer 1

首先获取get（）集合，然后将其转换为数组（toArray（））

$statsMoneyInPlay = DB::table('enginepoker_log.poker')
                                ->selectRaw("SELECT UNIX_TIMESTAMP(Date(ts)*100 as ts)")
                                ->selectRaw("sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay")
                                ->groupBy("Date(ts)")
                                ->orderBy("Date(ts)")
                                ->get()
                                ->toArray();

Answer 2

$statsMoneyInPlay = DB::table('enginepoker_log.poker')
    ->selectRaw("SELECT UNIX_TIMESTAMP(Date(ts)*100 as ts)")
    ->selectRaw("sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay")
    ->groupBy("Date(ts)")
    ->orderBy("Date(ts)")

返回一个Eloquent Query Builder instance。就像MySQL查询一样。实际上，它不从数据库中获取数据。

您需要执行该查询才能从数据库中获取数据。

这样做。调用get()函数到Eloquent Query Builder instance。

$statsMoneyInPlay = DB::table('enginepoker_log.poker')
    ->selectRaw("SELECT UNIX_TIMESTAMP(Date(ts)*100 as ts)")
    ->selectRaw("sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay")
    ->groupBy("Date(ts)")
    ->orderBy("Date(ts)")
    ->get()
    ->toArray();

调用未定义的方法Illuminate / Database / Query / Builder :: toArray（）
