如何将原生 PHP 转换为查询构建器 Laravel？

Question

如何从原生 php 转换为查询构建器 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，但仍然出现错误。 这就是错误

(2/2) QueryException SQLSTATE[42000]: 语法错误或访问 违规：1064 您的 SQL 语法有错误；检查手册 对应于正确语法的 MariaDB 服务器版本 在 'SELECT UNIX_TIMESTAMP(Date(ts)*100 as ts) 附近使用，sum(pot + p1pot + p2pot + p3pot + p4p' 在第 1 行（SQL：选择 SELECT UNIX_TIMESTAMP(日期(ts)100 as ts), sum(pot + p1pot + p2pot + p3pot + p4pot + p5pot + p6pot + p7pot + p8pot + p9pot) / count() As moneyInPlay 来自enginepoker_log.poker group by Date(ts) order 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();

这是在刀片页面中

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

您要查找的查询应该看起来更像这样：

$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，您可以通过以下方式访问元素：

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