GRANT

Last Updated：2023-07-28 02:55:43 Updated

Purpose

System administrators can use this statement to grant object privileges, system privileges, and roles to users.

Note

To grant object privileges, you must be the owner of the object, or have the GRANT OPTION privilege and the privileges to be granted. For example, if user1 wants to grant the SELECT privilege on the tbl1 table to user2, user1 must have the GRANT OPTION privilege and the SELECT privilege on tbl1.
To grant system privileges or roles to a user, you must have the GRANT OPTION privilege and the privileges or roles to be granted.
After a user is granted a role, the privileges of the role takes effect only after the user reconnects to OceanBase Database.
The privileges directly granted to a user take effect immediately.
