Hi Everyone,       
I added this query and added attr_accessor "balance_amount" and 
"booking_customer_id" in customers table, my query sets the value on 
attribute accessor but I am not able to fetch it from the dataset result, 
the query is: 

           SELECT * from customers
>             LEFT JOIN
>             (
>               SELECT cr.booking_customer_id, current_balance - 
> coalesce(booking_amount, 0) as balance_amount
>               FROM (Distinct record from table 2, i.e. bookings) cr
>               RIGHT JOIN (Distinct record from table 3, e.g. balance) cb
>               ON (booking_customer_id = balance_customer_id)
>             ) cwr
>             ON (customers.id = cwr.bookings_customer_id)


when I do, dataset.all and It shows `balance_amount` in the results,  try 
to fetch like: `dataset.all.first.balance_amount` it returns nil. What am I 
doing wrong here?

Thanks :)
