你好！我一直在努力从这个模式中获取记录，真的不适合我..关系太混乱了

PatPlan 表的 Ordinal 字段是 INT (1,2)
1= 主要保险
2= 次要保险

和关系字段（有基本保险的患者和有预约的患者之间的关系）的工作方式相同
1 = 自己
2 = 配偶
3 = 孩子

并且 inssub 表订阅者是患者

我需要获得基本上 3 大类：

1. Appointment's Fields
   -AptDateTime
   -DateTStamp
   -Patient's FirstName
   -Patient's LastName
   -Patient's Gender
   -Patient's Position
   -Patient's EmployerName


2. Guarantor's fields 
   //Same as the Patient's fields (Guarantor is a patient)
   //Must be the guarantor related to the patient who has the appointment
   -Patient's FirstName
   -Patient's LastName
   -Patient's Gender
   -Patient's Position
   -Patient's EmployerName
   -CarrierName
   -EmployerName

3. Primary Insurance (This is the one i can't work it out)
   //Primary insurance is as same as the patient's table
   -Patient's FirstName
   -Patient's LastName
   -Patient's Gender
   -Patient's Position
   -Patient's EmployerName
   -CarrierName
   -EmployerName

感谢您的帮助，因为我已经在这 3 天里工作了，但我还没有解决它。

我当前的查询：

SELECT p.Title, p.FName, p.LName, p.Position, p.Gender,e.EmpName, 

pm.FName AS PMFname, pm.LName AS PMLName, pp.Relationship AS PMPatStatus, 
pme.EmpName AS PMEmpName, i.DateEffective AS PMDateEffective, i.DateTerm AS PMDateTerm, 
c.CarrierName AS PMCarrierName, pme.EmpName AS PMEmpName,

g.FName AS GFName, g.LName AS GLName, pp.Relationship AS GPatStatus, g.Gender AS GGender,ge.EmpName AS GEmpName,

a.AptDateTime, a.AptNum, a.PatNum

FROM patient p LEFT OUTER JOIN Employer e ON p.employerNum = e.employerNum
inner JOIN Appointment a ON a.PatNum = p.PatNum
left JOIN Insplan ip ON ip.EmployerNum = e.employerNum
left JOIN Carrier c ON c.carrierNum = ip.carrierNum 
left JOIN Inssub i ON i.PlanNum = ip.PlanNum 
left JOIN patplan pp ON  pp.InsSubNum = i.InsSubNum AND  pp.PatNum = p.PatNum 
left JOIN Patient pm ON pm.PatNum = i.subscriber 
left JOIN Employer pme ON pme.employerNum = pm.employerNum
left JOIN Patient g ON g.PatNum = p.Guarantor 
LEFT JOIN Employer ge ON ge.employerNum = g.employerNum

WHERE a.DateTStamp > '2012/06/03' AND 
a.AptDateTime != '0001-01-01 00:00:00'
