取出序列ORA-01002

Question

您可以在下面查看并帮助我。我正在获取序列错误和ref cur值而不插入对象类型。

object (x,y,z)
type a is table of object

procedure a_procedure(a out a_ref cursor, b out b_ref cursor)is

x a := a();

begin
b_procedure(ref cursor)
if ref cursor%found then
loop
a.extend;
a(a.count) := object(null,null,null)
fetch ref cursor into a(a.count).x
                    a(a.count).y
                    a(a.count).y;
exit when b_refcur%notfound;
end loop;
end;
/

上下文：值不是从b_procedure的ref游标中获取的。我想从另一个过程获取ref游标值，并将该值提取到对象中。

Answer 1

begin
b_procedure (ref_cursor);
if ref_cursor%is open then
fetch ref_cursor into r`enter code here`ecord;
collection_type.extend;
collection_type(collection_type.last):=object(record.value1),
                                             (record.value2),
                                              ...etc);
end if;
end;
