Du kan göra så här:
select
audit_log_entries.created_at,
audit1.name as originator,
audit2.name as terminator
from audit_log_entries
join audit_log_orig_term_types audit1 on audit_log_entries.originator_type_id = audit1.id
join audit_log_orig_term_types audit2 on audit_log_entries.terminator_type_id = audit2.id;
