一开始这样写的：
select count(1) into v_sum_cnt,
sum(case
when (a.customer_status is null or
(a.latest_assigned_date <= add_months(sysdate, -6) and
a.customer_status = 'assigned')) then
1
else
0
end)
into v_kxf_cnt,
sum(case
when (a.customer_status is null or
(a.latest_assigned_date <= add_months(sysdate, -6) and
a.customer_status = 'assigned')) then
0
else
1
end)
into v_bkxf_cnt
from cls_customer_info a, dm_custlist_upload_batch b
where a.upload_batch_id = b.batch_id
and a.upload_batch_id = IN_UPLOAD_BATCH_ID
;
编译时就报错咯：编译错误 PL/SQL: ORA-00934: group function is not allowed here.
