Php 这些Laravel查询绑定不起作用

为什么我的Laravel查询绑定不起作用

此查询在MySqlWorkbench中工作：

SELECT 
    COUNT(id) AS AC_Leads,
    SUM(IF(webinarMinsWatched > 0, 1, 0)) AS startedWebinar,
    SUM(IF(webinarMinsWatched >= 47.23, 1, 0)) AS reachedCta
FROM
    contacts
WHERE
    DATE_FORMAT(created_at, '%Y-%m-%d') = '2017-05-06'
        AND adId = '6000689619221'
GROUP BY adId

这是我的拉威尔密码。不幸的是，它返回一个空数组，与上面的原始MySql不同，后者返回正确的结果：

$webinarCta = '47.23';
$adId = "6000689619221";
$dateStr = "2017-05-06";
DB::enableQueryLog();
$statsQuery = DB::table('contacts')
        ->selectRaw('COUNT(id) as AC_Leads, SUM(IF(webinarMinsWatched > 0, 1, 0)) as startedWebinar, SUM(IF(webinarMinsWatched >= ?, 1, 0)) as reachedCta', [(float) $webinarCta])
        ->whereRaw("DATE_FORMAT(created_at, '%Y-%m-%d') = '?'", [$dateStr])
        ->whereRaw("adId = '?'", [(int) $adId])
        ->groupBy('adId');
print_r($statsQuery->toSql());
echo '<hr>';
$stats = $statsQuery->get();
print_r($stats);
echo '<hr>';
Log::debug(DB::getQueryLog());
dd(DB::getQueryLog());

这是最终对我有效的查询。在？周围没有引号

谢谢，@Razor.

我认为绑定不应该被引用，用？替换“？”，并且不要向intThank扔$adId，@Razor；是的，我认为引用可能是问题所在。
