C# SQL完全联接6个表

我有几张桌子。有人能告诉我必须使用哪个连接吗

Table Factory : FactoryId, FactoryName

Table Person: PersonId, PersonName

Table Activity : AcitivityId, AcitivityType

Table FactoryPersonActivity: FactoryID, PersonId, ActivityId

Table AcitivityLead: AcitivityId, LeadId

Table Lead: LeadId, LeadType, LeadMethod

现在的问题是：我想要某个工厂的所有线索（细节）。有人能告诉我join语句必须是什么吗

提前谢谢

试试这个：

SELECT 
  l.LeadType,
  l.LeadMethod
  f.Name
  p.PersonNASme,
  ...
FROM Factory f 
INNER JOIN FactoryPersonActivity fpa ON f.FactoryId    = fpa.FactoryID
INNER JOIN Person                  p ON fpa.PersonID   = p.PersonId
INNER JOIN Activity                a ON fpa.ActivityID = a.ActivityId
INNER JOIN AcitivityLead          al ON a.AcitivityId  = al.AcitivityId
INNER JOIN Lead                    l ON a.LeadId       = al.LeadId
WHERE f.FactoryID = $id;
