Question

The BLOCK ACCESS command can be used to prevent other users from updating a specific table.

A) True
B) False

Answer 1

The statement is false; there is no 'BLOCK ACCESS' SQL command. Access control to prevent updates to a specific table is managed through SQL permissions with commands like GRANT and REVOKE.

Step-by-step explanation:

The statement "The BLOCK ACCESS command can be used to prevent other users from updating a specific table." is false. While the intention to prevent other users from updating a specific table is possible in the realm of database management, there is no standard SQL command called 'BLOCK ACCESS'. Instead, access control is managed through SQL permissions and transaction controls, such as the GRANT and REVOKE commands, which can give or take away privileges like SELECT, INSERT, UPDATE, and DELETE, or the use of transactions with appropriate isolation levels.
