Oracle ORA-06512 - PL/SQL: 数值或值错误 % s

问题描述

抱歉... 这与今天早些时候回答的上一个问题有关，但我不知道如何提出 “跟进” 问题...


我已经编写了下面的代码，以生成有关最近15天内未登录的实例中的用户的电子邮件报告。

我试图添加一个变量 (V_DAYS)，以便报告显示上次登录的天数，但是我收到以下错误...

错误报告:
ORA-06502: PL/SQL: 数值或值错误
ORA-06512: 在第34行
06502. 00000 - "PL/SQL: 数字或值错误 % s"

我相信这是我分配V_DAYS变量的数据类型和TRUNC(SYSDATE)-trunc (last_login) 的数据类型之间的某种不匹配，但我似乎无法将其固定下来。它在如下所示的FETCH C1处抛出错误...

选择到光标中的SQL工作，并给我用户名，las登录和自上次登录以来的天数。

如果我删除变量并且不尝试添加此第3列，则报告将正常执行并按预期生成电子邮件。

任何建议将不胜感激。谢谢!

专家解答

不是 “天”，而是last_login的长度 (这是时间戳)

例如，即使几天被完全删除，你也会得到错误
