Oracle 将子查询分解的输出存储在批量收集中

我想将查询的输出存储在

WITH 
  with_b AS
  (
   Select A, B from Table1
  )
SELECT * 
  FROM 

   (Select A, B from Table2) a, with_b b
WHERE a.A = b.A(+)
order by a.A;

---

进入批量收集。

您需要定义与最终查询投影匹配的收集类型。在给定的代码中，这将是

表2

中的两列，然后是

表1

中的两列

大概是这样的：

declare
    type ab_rec is record (
       a2 table2.a%type
       , b2 table2.b%type
       , a1 table1.a%type
       , b1 table1.b%type
    );
   type ab_nt is table of ab_rec;
   l_recs ab_nt;
begin
   WITH
    with_b AS
      (
        Select A, B from Table1
      )
    SELECT *
      bulk collect into  l_recs 
    FROM 
          (Select A, B from Table2) a, with_b b
          WHERE a.A = b.A(+)
          order by a.A;
 .....
end;
