MARIADB-SHOW(1) MariaDB Database System MARIADB-SHOW(1)
mariadb-show - display database, table, and column information
(mysqlshow is now a symlink to mariadb-show)
mysqlshow [options] [db_name [tbl_name [col_name]]]
The mysqlshow client can be used to quickly see which databases
exist, their tables, or a table´s columns or indexes.
mysqlshow provides a command-line interface to several SQL SHOW
statements. The same information can be obtained by using those
statements directly. For example, you can issue them from the
mysql client program.
Invoke mysqlshow like this:
shell> mysqlshow [options] [db_name [tbl_name [col_name]]]
• If no database is given, a list of database names is shown.
• If no table is given, all matching tables in the database are
shown.
• If no column is given, all matching columns and column types
in the table are shown.
The output displays only the names of those databases, tables, or
columns for which you have some privileges.
If the last argument contains shell or SQL wildcard characters
(“*”, “?”, “%”, or “_”), only those names that are matched by the
wildcard are shown. If a database name contains any underscores,
those should be escaped with a backslash (some Unix shells
require two) to get a list of the proper tables or columns. “*”
and “?” characters are converted into SQL “%” and “_” wildcard
characters. This might cause some confusion when you try to
display the columns for a table with a “_” in the name, because
in this case, mysqlshow shows you only the table names that match
the pattern. This is easily fixed by adding an extra “%” last on
the command line as a separate argument.
mysqlshow supports the following options, which can be specified
on the command line or in the [mysqlshow] and [client] option
file groups. mysqlshow also supports the options for processing
option files described.
• --help, -?
Display a help message and exit.
• --character-sets-dir=path, -c path
The directory where character sets are installed.
• --compress, -C
Compress all information sent between the client and the
server if both support compression.
• --count
Show the number of rows per table. This can be slow for
non-MyISAM tables.
• --debug[=debug_options], -# [debug_options]
Write a debugging log. A typical debug_options string is
´d:t:o,file_name´. The default is ´d:t:o´.
• --debug-check
Print some debugging information when the program exits.
• --debug-info
Print debugging information and memory and CPU usage
statistics when the program exits.
• --default-auth=name
Default authentication client-side plugin to use.
• --default-character-set=charset_name
Use charset_name as the default character set.
• --defaults-extra-file=filename
Set filename as the file to read default options from after
the global defaults files has been read. Must be given as
first option.
• --defaults-file=filename
Set filename as the file to read default options from,
override global defaults files. Must be given as first
option.
• --defaults-group-suffix=suffix
In addition to the groups named on the command line, read
groups that have the given suffix.
• --host=host_name, -h host_name
Connect to the MariaDB server on the given host.
• --keys, -k
Show table indexes.
• --no-defaults
Do not read default options from any option file. This must
be given as the first argument.
• --password[=password], -p[password]
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,
mysqlshow 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.
• --pipe, -W
On Windows, connect to the server via a named pipe. This
option applies only if the server supports named-pipe
connections.
• --plugin-dir=dir_name
Directory for client-side plugins.
• --port=port_num, -P port_num
The TCP/IP port number to use for the connection. Forces
--protocol=tcp when specified on the command line without
other connection properties.
• --protocol={TCP|SOCKET|PIPE|MEMORY}
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.
• --print-defaults
Print the program argument list and exit. This must be given
as the first argument.
• --show-table-type, -t
Show a column indicating the table type, as in SHOW FULL
TABLES. The type is BASE TABLE or VIEW.
• --socket=path, -S path
For connections to localhost, the Unix socket file to use,
or, on Windows, the name of the named pipe to use. Forces
--protocol=socket when specified on the command line without
other connection properties; on Windows, forces
--protocol=pipe.
• --ssl
Enable SSL for connection (automatically enabled with other
flags). Disable with --skip-ssl.
• --ssl-ca=name
CA file in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-capath=name
CA directory (check OpenSSL docs, implies --ssl).
• --ssl-cert=name
X509 cert in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-cipher=name
SSL cipher to use (check OpenSSL docs, implies --ssl).
• --ssl-key=name
X509 key in PEM format (check OpenSSL docs, implies --ssl).
• --ssl-crl=name
Certificate revocation list (check OpenSSL docs, implies
--ssl).
• --ssl-crlpath=name
Certificate revocation list path (check OpenSSL docs, implies
--ssl).
• --ssl-verify-server-cert
Verify server's "Common Name" in its cert against hostname
used when connecting. This option is disabled by default.
• --status, -i
Display extra information about each table.
• --user=user_name, -u user_name
The MariaDB user name to use when connecting to the server.
• --verbose, -v
Verbose mode. Print more information about what the program
does. This option can be used multiple times to increase the
amount of information.
• --version, -V
Display version information and exit.
