shell> mysqlcheck test t
test.t
note     : The storage engine for the table doesn´t support check

It is best to make a backup of a table before performing a table repair operation; under some circumstances the operation might cause data loss. Possible causes include but are not limited to file system errors.

shell> mysqlcheck [options] db_name [tbl_name ...]
shell> mysqlcheck [options] --databases db_name ...
shell> mysqlcheck [options] --all-databases

Display a help message and exit.

Check all tables in all databases. This is the same as using the --databases option and naming all the databases on the command line.

Instead of issuing a statement for each table, execute a single statement for each database that names all the tables from that database to be processed.

Analyze the tables.

If a checked table is corrupted, automatically fix it. Any necessary repairs are done after all tables have been checked.

The directory where character sets are installed. See Section 9.5, “Character Set Configuration”.

Check the tables for errors. This is the default operation.

Check only tables that have changed since the last check or that have not been closed properly.

Invoke CHECK TABLE with the FOR UPGRADE option to check tables for incompatibilities with the current version of the server. This option automatically enables the --fix-db-names and --fix-table-names options. --check-upgrade was added in MySQL 5.1.7.

Compress all information sent between the client and the server if both support compression.

Process all tables in the named databases. Normally, mysqlcheck treats the first name argument on the command line as a database name and following names as table names. With this option, it treats all name arguments as database names.

Write a debugging log. A typical debug_options string is ´d:t:o,file_name´. The default is ´d:t:o´.

Print some debugging information when the program exits. This option was added in MySQL 5.1.21.

Print debugging information and memory and CPU usage statistics when the program exits. This option was added in MySQL 5.1.14.

Use charset_name as the default character set. See Section 9.5, “Character Set Configuration”.

Set filename as the file to read default options from after the global defaults files has been read. Must be given as first option.

Set filename as the file to read default options from, override global defaults files. Must be given as first option.

If you are using this option to check tables, it ensures that they are 100% consistent but takes a long time.

If you are using this option to repair tables, it runs an extended repair that may not only take a long time to execute, but may produce a lot of garbage rows also!

Check only tables that have not been closed properly.

Convert database names to 5.1 format. Only database names that contain special characters are affected. This option was added in MySQL 5.1.7.

Convert table names to 5.1 format. Only table names that contain special characters are affected. This option was added in MySQL 5.1.7. As of MySQL 5.1.23, this option also applies to views.

Continue even if an SQL error occurs.

Connect to the MySQL server on the given host.

Do a check that is faster than an --extended operation. This finds only 99.99% of all errors, which should be good enough in most cases.

Do not read default options from any option file. This must be given as the first argument.

Optimize the tables.

The password to use when connecting to the server. If you use the short option form (-p), you cannot have a space between the option and the password. If you omit the password value following the --password or -p option on the command line, mysqlcheck prompts for one.

Specifying a password on the command line should be considered insecure. See Section 5.3.2.2, “End-User Guidelines for Password Security”. You can use an option file to avoid giving the password on the command line.

On Windows, connect to the server via a named pipe. This option applies only if the server supports named-pipe connections.

The TCP/IP port number to use for the connection.

The connection protocol to use for connecting to the server. It is useful when the other connection parameters normally would cause a protocol to be used other than the one you want. For details on the allowable values, see Section 4.2.2, “Connecting to the MySQL Server”.

Print the program argument list and exit. This must be given as the first argument.

If you are using this option to check tables, it prevents the check from scanning the rows to check for incorrect links. This is the fastest check method.

If you are using this option to repair tables, it tries to repair only the index tree. This is the fastest repair method.

Perform a repair that can fix almost anything except unique keys that are not unique.

Silent mode. Print only error messages.

For connections to localhost, the Unix socket file to use, or, on Windows, the name of the named pipe to use.

Options that begin with --ssl specify whether to connect to the server via SSL and indicate where to find SSL keys and certificates. See Section 5.5.6.3, “SSL Command Options”.

Override the --databases or -B option. All name arguments following the option are regarded as table names.

For repair operations on MyISAM tables, get the table structure from the .frm file so that the table can be repaired even if the .MYI header is corrupted.

The MySQL user name to use when connecting to the server.

Verbose mode. Print information about the various stages of program operation.

Display version information and exit.

This option is enabled by default, so that ANALYZE TABLE, OPTIMIZE TABLE, and REPAIR TABLE statements generated by mysqlcheck are written to the binary log. Use --skip-write-binlog to cause NO_WRITE_TO_BINLOG to be added to the statements so that they are not logged. Use the --skip-write-binlog when these statements should not be sent to replication slaves or run when using the binary logs for recovery from backup. This option was added in MySQL 5.1.18.
