How can we get the difference (No. of columns/records/permissions) between two different tables/views?
For example:
We have two views USER_TABLES and USER_EXTERNAL_TABLES. Now how can I get the all/some difference(s) between them?
Regards. |

You can check number of columns from user_tab_columns view. Use minus operator.
e.g. select column_name from user_tab_columns where table_name = 'A'
minus
select column_name from user_tab_columns where table_name = 'B';
you can do the same for records as well. Use the actual table name when use minus.
