Select 游标中的查询选择错误

我的选择光标有问题。Select在其他窗口正常工作，但我在使用光标的过程中出错。为什么？ 我更改了Tabele和数据库的名称，但在这个过程之外选择OK

我的错误： PL/SQL:ORA-04052： ORA-00604： ORA-03106：

通过添加异常块，您可以尝试处理您遇到的错误吗

你得到了什么类型的错误？好的，我编辑了文章，我写了错误，我想这与权限有关。当您执行plsql过程时，请检查您通过dblink访问的表是否具有权限。我认为这是可以的，因为选择它在该过程之外工作。我无法编译，也不知道我得到了什么。PL/SQL:ORA-04052:ORA-00604 ORA-03106授予执行SQL的权限是什么？对于plsql，您需要显式授予权限。确定问题已解决！！我创建此视图，在光标中选择并使用视图
