我写了一个程序，试图将值从源表插入到目标表，为了执行大量数据，我使用了批量收集。
在执行下面的过程时，它的showing cursor cus2声明不完整，并且它的showing cursor中的某些列定义不明确。

create or replace PROCEDURE TEST2 (
    p_array_size IN NUMBER
) IS

CURSOR cur1 IS SELECT DISTINCT
        *
                        FROM
        test

        CURSOR cur3 IS SELECT * FROM test;

对我来说一切都很好，找不到确切的错误。有人能帮我解决这个问题吗。
