shell> mysqlcheck 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.

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.

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.

Print debugging information and memory and CPU usage statistics when the program exits.

Default authentication client-side plugin to use.

Use charset_name as the default character set.

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 will force using the old, slow, repair with keycache method, instead of the much faster repair by sorting.

Check only tables that have not been closed properly.

Convert database names to the format used since MySQL 5.1. Only database names that contain special characters are affected.

Convert table names (including views) to the format used since MySQL 5.1. Only table names that contain special characters are affected.

Flush each table after check. This is useful if you don't want to have the checked tables take up space in the caches after the check.

Continue even if an SQL error occurs.

Connect to the MariaDB 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. You can use an option file to avoid giving the password on the command line.

Used with ANALYZE TABLE to append the option PERSISENT FOR ALL.

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

Directory for client-side plugins.

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

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

Perform the requested operation on tables. Defaults to on; use --skip-process-tables to disable.

Perform the requested operation (only CHECK VIEW or REPAIR VIEW). Possible values are NO, YES (correct the checksum, if necessary, add the mariadb-version field), UPGRADE_FROM_MYSQL (same as YES and toggle the algorithm MERGE<->TEMPTABLE.

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.

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.

Don't process the database (case-sensitive) specified as argument.

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

Enable SSL for connection (automatically enabled with other flags). Disable with --skip-ssl.

CA file in PEM format (check OpenSSL docs, implies --ssl).

CA directory (check OpenSSL docs, implies --ssl).

X509 cert in PEM format (check OpenSSL docs, implies --ssl).

SSL cipher to use (check OpenSSL docs, implies --ssl).

X509 key in PEM format (check OpenSSL docs, implies --ssl).

Certificate revocation list (check OpenSSL docs, implies --ssl).

Certificate revocation list path (check OpenSSL docs, implies --ssl).

Verify server's "Common Name" in its cert against hostname used when connecting. This option is disabled by default.

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 MariaDB user name to use when connecting to the server.

Verbose mode. Print information about the various stages of program operation. Using one --verbose option will give you more information about what mysqlcheck is doing.

Using two --verbose options will also give you connection information.

Using it 3 times will print out all CHECK, RENAME and ALTER TABLE during the check phase.

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.
