表或视图不存在

标签: oracle plsql execute execute-immediate

下面给出的是我的代码。我需要使用视图中的数据创建一个视图并在另一个游标中获取数据。但是当我执行我的代码时,我收到了错误

“ORA-06550:第56行,第37栏: PL / SQL:ORA-00942:表或视图不存在 ORA-06550:第52行,第9栏: PL / SQL:SQL语句忽略“

这是什么问题? 提前谢谢。

您正在尝试访问使用动态 TABLE/VIEW在您SQL的同一个区块中创建的SELECT(静态{{1} })

执行之前,

每个SQL阻止编译。 虽然汇编PL/SQL不可用!

所以,rv_task_number_view也需要是动态的!

SELECT
