NAME         top

       mysqlshow - display database, table, and column information

SYNOPSIS         top

       mysqlshow [options] [db_name [tbl_name [col_name]]]

DESCRIPTION         top

       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.

           Display version information and exit.
