Hello!  Can you provide me with the first and last name of the customer who has account name 900?
select t2.customer_first_name, t2.customer_last_name from accounts as t1 join customers as t2 on t1.customer_id = t2.customer_id where t1.account_name = "900"
Great!  Could you update this list to show me Meaghan's email address and phone number as well?
select t2.customer_first_name, t2.customer_last_name, t2.email_address, t2.phone_number from accounts as t1 join customers as t2 on t1.customer_id = t2.customer_id where t1.account_name = "900"
Great! Finally, can you show me all other customers names (first and last) who have the same "other account details" details as Meaghan?
select distinct t2.customer_first_name, t2.customer_last_name from accounts as t1 join customers as t2 on t1.customer_id = t2.customer_id where t1.other_account_details = ( select other_account_details from accounts where account_name = 900 )
