MySQL account information is stored in the tables of the mysql system schema. This database and the access control system are discussed extensively in Chapter 7, MySQL Server Administration, which you should consult for additional details.

Important

Some MySQL releases introduce changes to the grant tables to add new privileges or features. To make sure that you can take advantage of any new capabilities, update your grant tables to the current structure whenever you upgrade MySQL. See Chapter 3, Upgrading MySQL.

When the read_only system variable is enabled, account-management statements require the CONNECTION_ADMIN privilege (or the deprecated SUPER privilege), in addition to any other required privileges. This is because they modify tables in the mysql system schema.

Account management statements are atomic and crash safe. For more information, see Section 15.1.1, “Atomic Data Definition Statement Support”.
