选择内部循环oracle

Question

我编写了一个存储过程，其中包含一个循环内的查询。 此查询将记录设置为 RECORD 类型的自定义数据类型，例如

TYPE finalrecord
IS
  RECORD
  (
    corh           VARCHAR2(1),
    myspissueid    NUMBER(10),
    mypkey         VARCHAR2(10),
    mycreated      DATE,
    myprevstepname VARCHAR2(10),
    mystepname     VARCHAR2(10),
    mystorypoints  NUMBER(2) );

  myfinalrecord finalrecord;

for 循环是这样的

for vh in (select * from table1 where abc=3)
loop

select steps.current_or_history,
    steps.issueid,
    steps.pkey,
    steps.created,
    steps.prev_step_name,
    steps.step_name,
    steps.story_points

from steps where column1 = 'xyz' and column2=vh.column2;


end loop;

每次执行内部循环时，SELECT 语句都会返回多条记录。我想将此记录添加到主变量（作为集合..但可变数组或嵌套表或关联数组）并将该变量作为存储过程的输出返回。

有什么想法吗？

Answer 1

declare
  type t is table of finalrecord;
  my_table t;
begin
  for vh in (select * from table1 where abc = 3) loop

    execute immediate 'select finalrecord(steps.current_or_history,
        steps.issueid,
        steps.pkey,
        steps.created,
        steps.prev_step_name,
        steps.step_name,
        steps.story_points)

    from steps where column1 = ''xyz'' and column2=vh.column2' bulk
                      collect
      into my_table;

  end loop;
end;

如果可行，你可以试试这个，你也可以创建过程...
