如何从你不拥有的oracle表中获取列信息（不使用describe）？

Question

如何在桌面上获取他不拥有的列信息，但是已选择授予？这是，不使用DESCRIBE table_name。考虑这个例子：

// user bob owns table STUDENTS
grant select on students to josh;
// now josh logs in, normally he would do
describe bob.students;
// but he's looking for something along the lines
select column_name from user_tab_columns where table_name = 'STUDENTS';
// which doesn't work, as josh doesn't own any tables on his own

有什么想法吗？这甚至可行吗？

Answer 1

select column_name from all_tab_columns where table_name = 'STUDENTS';

编辑或者，甚至更好

select owner, column_name from all_tab_columns where table_name = 'STUDENTS';

Answer 2

看看oracle data dictionary，它应该会有所帮助。

Answer 3

CONN HR/HR@HSD;

GRANT SELECT ON EMPLOYEES TO SCOTT;

CONN SCOTT/TIGER@HSD;

SELECT owner, column_name FROM all_tab_columns WHERE table_name = 'EMPLOYEES';
