Description

The GRANT command is used to grant access privileges for users to tables. It can extend user privileges but cannot limit existing privileges. Later GRANT statements do affect privileges already granted to a user. Privileges can only be removed with the REVOKE statement. To grant privileges you must be the owner of the table or have already been granted ALTER privileges.
