如何从本地php转换为查询生成器laravel

$statsMoneyInPlay = array(); 
    $sql_query = "SELECT UNIX_TIMESTAMP(Date(ts))*1000 As ts, sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay FROM enginepoker_log.poker WHERE GROUP BY Date(ts) ORDER BY Date(ts) LIMIT 30 ";

，我已经创建了查询生成器，但是仍然出现错误。这是错误

（2/2）QueryException SQLSTATE [42000]：语法错误或访问违反：1064您的SQL语法有错误；查看手册对应于您的MariaDB服务器版本的正确语法在'SELECT UNIX_TIMESTAMP（Date（ts）* 100 as ts），sum（pot + 第1行的p1pot + p2pot + p3pot + p4p'（SQL：选择SELECT UNIX_TIMESTAMP（Date（ts） 100 as ts），sum（pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot）/ count（）为 enginepoker_log组的poker。Date(ts)组的moneyInPlay 由Date(ts) asc）

这是查询生成器：

$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)")
                                ->get()
                                ->toArray();

这在刀片页面中

@php
foreach ($statsMoneyInPlay as $key => $value) {
echo "[".$value[0].", ".$value[1]."],";
@endphp

您要查询的查询看起来应该像这样：

$statsMoneyInPlay = DB::table('enginepoker_log.poker')
 ->select(
   DB::raw("UNIX_TIMESTAMP(Date(ts)*100) as timestamp"),
   DB::raw("SUM(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count(*) As moneyInPlay")
 )
 ->groupBy(DB::raw("DATE(ts)"))
 ->orderByRaw("DATE(ts)")
 ->get()
 ->toArray();

在刀片中，您可以通过以下操作访问元素：

foreach($statsMoneyInPlay as $stat) {
  echo "[" . $stat->timestamp . ", " . $stat->moneyInPlay . "]";
}
