我有一個問題，有三個表

Table A 

ID  Employee  
1   1  
2   2 
3   3 


Table B 
Id  EMployee  HoursWorked   HoursCode 
1   1     10    Basic Hours 
2   1     20    Holiday Pay 
3   2     10    Basic hours 
4   2     15    OverTime 

Table C 
ID  Employee   Payments   PayCode 
1   1     100    Bonus 
2   2     150    Bonus 
3   2     250    Student Loan 

我想記錄了在最短的線路，這些表的，所以我可以有一個線，說

id  Employee   Hour    HoursCode  Payments  PayCode 
1   1     10    Basic Hours  100   Bonus  
2   1     20    Holiday Pay  null   null 
3   2     10    basic hours  150   Bonus 
4   2     15     OverTime  250   Student loan 

我已經花了年齡試圖讓它...但不要讓空在它與100名獎金出來，在第二行員工1

2號線是有辦法可以做到這一點請幫助

WITH bn AS 
     (
     SELECT *, ROW_NUMBER() OVER (PARTITION BY employee ORDER BY id) AS rn 
     FROM b 
     ), 
     cn AS 
     (
     SELECT *, ROW_NUMBER() OVER (PARTITION BY employee ORDER BY id) AS rn 
     FROM c 
     ) 
SELECT * 
FROM bn 
FULL JOIN 
     cn 
ON  bn.employee = cn.employee 
     AND bn.rn = cn.rn 
ORDER BY 
     COALESCE(bn.employee, cn.employee), COALESCE(bn.rn, cn.rn)
