Php 使用DB:：Raw时，Laravel Join未按预期工作

因此，我得到的错误是

SQLSTATE[42S02]：未找到基表或视图：字段列表中的1109未知表“team_members”

因此，这种加入似乎并没有真正发生。有人看到代码中的问题吗

$data = DB::select(DB::raw('

                  production_hours.time_stop)) / 60 As hoursWorked,
                  production_activities.name As groupName,

那么，您要查询哪个表呢？您并没有在查询中指定。您只是在对其进行一般性的选择nothing@MarkBaker是的，我太傻了。
DB:：select（）
和
DB:：table（）->select（）之间有区别
-正如@MarkBaker指出的，第一个方法是调用
连接
对象的方法，它只运行查询，后者是
query\Builder
对象方法，可以按您需要的方式链接。
