       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. See
       Section 12.7.5, “SHOW Syntax”. 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] groups of an option file.  mysqlshow also supports the
       options for processing option files described at Section, “Command-Line Options
       that Affect Option-File Handling”.

       ·   --help, -?

           Display a help message and exit.

       ·   --bind-address=ip_address

           On a computer having multiple network interfaces, this option can be used to select
           which interface is employed when connecting to the MySQL server.

           This option is supported only in the version of mysqlshow that is supplied with MySQL
           Cluster. It is not available in standard MySQL Server 5.5 releases.

       ·   --character-sets-dir=path

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

       ·   --compress, -C

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

       ·   --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

       ·   --default-character-set=charset_name

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

       ·   --default-auth=plugin

           The client-side authentication plugin to use. See Section 5.5.6, “Pluggable

           This option was added in MySQL 5.5.10.

       ·   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       ·   --keys, -k

           Show table indexes.

       ·   --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. See
           Section, “End-User Guidelines for Password Security”. You can use an option
           file to avoid giving the password on the command line.

       ·   --pipe, -W

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

       ·   --plugin-dir=path

           The directory in which to look for plugins. It may be necessary to specify this option
           if the --default-auth option is used to specify an authentication plugin but mysqlshow
           does not find it. See Section 5.5.6, “Pluggable Authentication”.

           This option was added in MySQL 5.5.10.

       ·   --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. For details on the permissible values, see Section 4.2.2, “Connecting to
           the MySQL Server”.

       ·   --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*

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

       ·   --status, -i

           Display extra information about each table.

       ·   --user=user_name, -u user_name

           The MySQL 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.
