Question

I have two tables like below

Book

id TID reserveddate fee1 fee2 fee3 Noofplayers total
-------------------------------------
1   11  2012-11-25 100  200  300      3        800
2   12  2012-11-25 100  200  300      3        800
3   13  2012-11-28 200  100  200      1        500

Players

 TID  fee1 fee2 
-------------------------------------
  11  100  200  
  11  100  200  
  11  100  200 
  12  100  200  
  12  100  200
  12  100  200
  13  200  100  

now i would like to retrieve data from both tables with group by Reserveddate.

I have a query,

select sum(b.fee1)+sum(b.fee2)+sum(a.fee3) as total 
from Players b,book a where a.TID = b.TID  and a.ReservedDate ='25-nov-2012' 
group by a.ReservedDate

the above query in sum(fee3) adding 3(noofplayers) times i want to add one time book table.

could you please update the query as per client requirement…

Answer 1

I believe this would work, it would give total of 2400:

select  sum(b.fee1_fee2_totalPerPlayer) + sum(a.fee3) as total 
from    book a
join    (
            select  TID,
                    sum(fee1) + sum(fee2) 
                        as fee1_fee2_totalPerPlayer
            from    Players
            group   by TID
        ) b on
        a.TID = b.TID
where   a.ReservedDate ='2012-11-25' 
group by a.ReservedDate

Here is how the total is getting calculated:

For TID=11: 300 (sum of Players.fee1) + 600 (sum of Players.fee2) = 900

For TID=12: 300 (sum of Players.fee1) + 600 (sum of Players.fee2) = 900

900 + 900 = 1800

1800 + 600 (sum of Book.fee3 for date ‘2012-11-25’) = 2400
