我运行了以下代码,一个小时后,就在代码完成时发生了排序执行错误。我的代码有问题还是我的计算机处理器和内存不足
proc sql;
create table today as
select a.account_number, a.client_type, a.device ,a.entry_date_est,
a.entry_time_est, a.duration_seconds, a.channel_name, b.esn, b.service_start_date,
b.service_end_date, b.product_name, b.billing_frequency_fee, b.plan_category,
b.plan_subtype, b.plan_type
from listen_nomiss a inner join service_nomiss b
on (a.account_number = b.account_number)
order by account_number;
quit;
