java.sql.SQLException: ORA-06530: 引用未初始化的组合

Question

不确定是什么导致了这个错误。我在我们的一个包中乱七八糟，并试图让一个过程与一些 Java 代码一起运行。你能告诉我我做错了什么吗？也许是 Java 或 SQL？

PROCEDURE update_object_comment (p_object_comment IN OUT objects_comment_bean, p_user_id IN user_list.user_id%TYPE)
IS
    t_object_comment objects_comment_bean;
BEGIN

    SELECT get_comments (p_object_comment.id,t_object_comment.type )
      INTO t_object_comment
      FROM DUAL;

    -- We only perform the update if something really changed
    IF NOT p_object_comment.equals (t_object_comment)
    THEN
        -- Copy what was in the database so that we are positive
        -- that the created information can never change.
        p_object_comment.auditable := t_object_comment.auditable;
-- <<<< <<<<<<<<<<<<<<<<<<<<<<IT SAYS THE ERROR IS HAPPENING HERE>>>>>>>>>>>>>>>>>>>>>>>>>>>
        -- The modified date has to be set on update (but not creation)
        p_object_comment.auditable.modified_date := SYSDATE;
        p_object_comment.auditable.modified_by := p_user_id;

        UPDATE object_comments
           SET comment = p_object_comment.comment,
               auditable = p_object_comment.auditable
         WHERE id = p_object_comment.id
         AND type = p_object_comment.type;


    END IF;

END update_object_comment;

找到答案：

SELECT get_comments (p_object_comment.id,t_object_comment.type ) 

应该是：

SELECT get_comments (p_object_comment.id,p_object_comment.type )
