In SQL, you can revoke privileges from multiple users by using the REVOKE
statement. This statement allows you to remove specific privileges that have been previously granted to one or more users.
The syntax for revoking privileges from multiple users is as follows:
REVOKE privilege_type
ON table_name
FROM user1, user2, user3...;
Here, privilege_type
refers to the specific privilege you want to revoke, such as SELECT
, INSERT
, UPDATE
, or DELETE
. table_name
is the name of the table from which you want to revoke the privilege.
To revoke privileges from multiple users, simply list the usernames separated by commas after the FROM
keyword.
Examples
Let’s say you want to revoke the SELECT
privilege from users named user1
, user2
, and user3
on a table called employees
. The SQL statement would be:
REVOKE SELECT
ON employees
FROM user1, user2, user3;
Likewise, if you want to revoke the INSERT
privilege from the same set of users, you can use the following statement:
REVOKE INSERT
ON employees
FROM user1, user2, user3;
By executing these REVOKE
statements, you will successfully remove the specified privileges from the designated users on the employees
table.
Remember to adjust the privilege_type
, table_name
, and user names to fit your specific requirements.
These were the steps to revoke privileges from multiple users in SQL. Use this feature responsibly to manage access control and security in your database environment.
