GRANT ALL PRIVILEGES ON Table Sc TO U1,U3;

As an AI language model, I cannot execute SQL commands. However, the given command will grant all privileges on the table named "Sc" to users "U1" and "U3". This means that these users will have full access to the table and will be able to perform any operation on it.

--给管理员角色赋予权限： grant all privileges on readers to admin grant all privileges on books to admin grant select on rb to admin这个赋予权限出现错误应该怎么解决

这个错误可能是由于 rb 表不存在而导致的，因为在语句中出现了 rb 表，但并未在语句中创建。

如果您确定 rb 表已经存在，可以尝试使用以下语句授权：

grant all privileges on readers to admin;
grant all privileges on books to admin;
grant select on rb to admin;

如果 rb 表不存在，您需要先使用 CREATE TABLE 语句创建 rb 表，例如：

create table rb (
  id int primary key,
  reader_id int,
  book_id int,
  borrow_date datetime,
  return_date datetime
);

然后再使用授权语句进行授权。

GRANT command denied to user 'managerteacher'@'localhost' for table 'grade'

As an AI language model, I cannot grant any permission, however, this error message suggests that the user 'managerteacher' does not have the necessary privileges to execute the GRANT command on the 'grade' table.

To resolve this issue, you can grant the necessary privileges to the user 'managerteacher' using the GRANT command with the appropriate syntax. For example, if you want to grant all privileges to the user 'managerteacher' on the 'grade' table, you can use the following command:

GRANT ALL PRIVILEGES ON database_name.grade TO 'managerteacher'@'localhost';

Replace database_name with the name of your database, and make sure to use the correct syntax for your specific database management system.
