Можно ли упростить данный sql запрос

Есть такой запрос к базе данных MySql

select FirstName, LastName, runner.Email, RegistrationStatus
from registrationevent
     inner join registration on registration.RegistrationId = registrationevent.RegistrationId 
     inner join registrationstatus on registration.RegistrationStatusId = registrationstatus.RegistrationStatusId 
     inner join runner on runner.RunnerId = registration.RunnerId 
     inner join user on user.Email = runner.Email
     inner join event on event.EventId = registrationevent.EventId 
     inner join eventtype on event.EventTypeId = eventtype.EventTypeId 
where RegistrationDateTime like '%2017%' and EventTypeName='Full Marathon'

Можно ли его упростить? И если можно, то как?
