The user SCOTT who is the owner of ORDERS and ORDER_ITEMS tables issues

the following GRANT command:

GRANT ALL ON orders, order_items TO PUBLIC;

What correction needs to be done to the above statement?

A. PUBLIC should be replaced with specific usernames.

B. ALL should be replaced with a list of specific privileges.

C. WITH GRANT OPTION should be added to the statement.

D. Separate GRANT statements are required for ORDERS and ORDER_ITEMS tables.

Answer: D

grant all to public;//这条比较重要，授予所有权限(all)给所有用户(public)

Eg:

SQL> GRANT ALL ON test,wdz1 TO PUBLIC
