MYSQLSHOW(1) MariaDB Database System MYSQLSHOW(1)
mysqlshow - display database, table, and column information
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.
· --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.
· --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.
