Question

这里我试图创建.csv文件来显示来自视图的两个字段数据，请它需要完整的如何创建csv文件

Answer 1

它与ORA-01403: no data found发生错误，因为您在代码中执行隐式游标（即。select ... into ...而不是cursor cur is select ...），并且如果没有返回任何行，你得到那个错误。所以你必须传入一个不存在的partner_id，导致选择失败。

通常，在使用隐式游标时，应确保处理两个异常条件：找不到数据和行太多。（在某些情况下，您不需要为过多的行异常而烦恼 - 例如，如果您在主键上进行选择，那么您将永远不会获得多行返回。）

请建议我为什么不执行程序：下面给出错误代码
