Enable SHOW DATABASES to show all databases. Level: Global. SHOW VIEW Enable use of SHOW CREATE VIEW. Levels: Global, database, table. SHUTDOWN Enable use of mysqladmin shutdown. Level: Global. SUPER Enable use of other administrative operations such as CHANGE REPLICATION SOURCE TO, CHANGE MASTER TO, KILL, PURGE BINARY LOGS, SET GLOBAL, and mysqladmin debug command. Level: Global. TRIGGER Enable trigger operations. Levels: Global, database, table. UPDATE Enable use of UPDATE. Levels: Global, database, table, column. USAGE Synonym for “no privileges” A trigger is associated with a table. To create or drop a trigger, you must have the TRIGGER privilege for the table, not the trigger. In GRANT statements, the ALL [PRIVILEGES] or PROXY privilege must be named by itself and cannot be specified along with other privileges. ALL [PRIVILEGES] stands for all privileges available for the level at which privileges are to be granted except for the GRANT OPTION and PROXY privileges. MySQL account information is stored in the tables of the mysql system schema. For additional details, consult Section 8.2, “Access Control and Account Management”, which discusses the mysql system schema and the access control system extensively. If the grant tables hold privilege rows that contain mixed-case database or table names and the lower_case_table_names system variable is set to a nonzero value, REVOKE cannot be used to revoke these privileges. It is necessary in such cases to manipulate the grant tables directly. (GRANT does not create such rows when lower_case_table_names is set, but such rows might have been created prior to setting that variable. The lower_case_table_names setting can only be configured at server startup.) Privileges can be granted at several levels, depending on the syntax used for the ON clause. For REVOKE, the same ON syntax specifies which privileges to remove. For the global, database, table, and routine levels,

mysqladmin - MySQL root@localhost, and

And that mysqld cannot resolve the host name for your client: Access denied for user ''@'unknown' These errors indicate a DNS problem. To fix it, execute mysqladmin flush-hosts to reset the internal DNS host cache. See Section 7.1.12.3, “DNS Lookups and the Host Cache”. Some permanent solutions are: Determine what is wrong with your DNS server and fix it. Specify IP addresses rather than host names in the MySQL grant tables. Put an entry for the client machine name in /etc/hosts on Unix or \windows\hosts on Windows. Start mysqld with the skip_name_resolve system variable enabled. Start mysqld with the --skip-host-cache option. On Unix, if you are running the server and the client on the same machine, connect to localhost. For connections to localhost, MySQL programs attempt to connect to the local server by using a Unix socket file, unless there are connection parameters specified to ensure that the client makes a TCP/IP connection. For more information, see Section 6.2.4, “Connecting to the MySQL Server Using Command Options”. On Windows, if you are running the server and the client on the same machine and the server supports named pipe connections, connect to the host name . (period). Connections to . use a named pipe rather than TCP/IP. If mysql -u root works but mysql -h your_hostname -u root results in Access denied (where your_hostname is the actual host name of the local host), you may not have the correct name for your host in the user table. A common problem here is that the Host value in the user table row specifies an unqualified host name, but your system's name resolution routines return a fully qualified domain name (or vice versa). For example, if you have a row with host 'pluto' in the user table, but your DNS tells MySQL that your host name is 'pluto.example.com', the row does not work. Try adding a row to the user table that contains the IP address of your host as the Host column value. (Alternatively, you could add a row to the user table with a Host value that contains a wildcard (for example, 'pluto.%'). However, use of Host values ending with % is insecure and is not recommended!) If mysql -u user_name works but mysql -u user_name some_db does not, you have not granted access to the given user for the database named some_db. If mysql -u user_name works when executed on.
