Re: Second left join for sum() sees previous left join instead of main table
I also solved sum field as this: Subscription.select{ (sum( Sequel[:bounty_packages][:storage_size]) + sum( Sequel[:subscription_packages][:storage_size])).as(:size) } Once again, Let me know if there is a better way.

Re: Second left join for sum() sees previous left join instead of main table
One thing thsat i couldn't solve is that how to fetch total sum column as :storage_size. select sum() + sum() as FIELD_NAME ... In my scenario, there are two sums and i need to name them.

Re: Second left join for sum() sees previous left join instead of main table
As per documentation, I achieved this by: Subscription.select{ sum( Sequel[:bounty_packages][:storage_size]) + sum( Sequel[:subscription_packages][:storage_size]) } .left_join(:subscription_packages, id: :subscription_package_id) .left_join(:bounty_packages, id: Sequel[:subscriptions][: bounty_package_id]) .where(user: user) Let me know if there is a better way. Thanks, Genc.

Second left join for sum() sees previous left join instead of main table
Hi Jeremy, This is my SQL query: select sum(sp.storage_size) + sum(bp.storage_size) as storage_size from subscriptions s left join subscription_packages sp on s.subscription_package_id = sp.id left join bounty_packages bp on s.bounty_package_id = bp.id where s.user_id = 4; However, second left join is always broken: Subscription.select{ sum(Sequel[:'bounty_packages.storage_size']) + sum( Sequel[:'subscription_packages.storage_size']) } .left_join(:subscription_packages, id: :subscription_package_id) .left_join(:bounty_packages, id: :bounty_package_id) # this join trying to join previous join (subscription_packages) not the main 'subscriptions' table .where(user: user) Is there a wiser way to accomplish my query with Sequel?
