PROCEDURE "ARCHIVE_CASE_LIST"
(
a_case_id_list IN INLISTNUMBERS
)
IS
l_customers INLISTNUMBERS;
INLISTNUMBERS是Oracle数字表;
如何准备预先计算的客户列表并将它们存储在l_customers中,这样我就不需要在其他更新/选择语句中使用那个长选择语句？
insert into table(l_customers) <-- fail
select distinct case1.customer_id into l_customers from case case1
where case1.case_id in (select column_value from table(a_case_id_list)) and
not exists (select 0 from case case2 where case2.customer_id = case1.customer_id and
case2.lifecycle_code not in (code_id('LIFECYCLE','A'),code_id('LIFECYCLE','D')));
update customer set customer.lifecycle_code = code_id('LIFECYCLE','A')
where customer.customer_id in (select column_value from table(l_customers));
open l_persons for
select person_id from person where person.customer_id in
(select column_value from table(l_customers));
使用带有BULK COLLECT的SELECT语句：

from case case1
where case1.case_id in (select column_value from table(a_case_id_list)) and
not exists (select 0 from case case2 where case2.customer_id = case1.customer_id and
case2.lifecycle_code not in (code_id('LIFECYCLE','D')));
