【问题描述】：

PROCEDURE "ARCHIVE_CASE_LIST"
(
    a_case_id_list IN INLISTNUMBERS
)
IS
  l_customers INLISTNUMBERS;

INLISTNUMBERS 是 Oracle 数字表；

我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的选择语句？

  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));

【解决方案1】：

使用带有 BULK COLLECT 的 SELECT 语句：

select distinct case1.customer_id bulk collect 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')));
