MYSQLSHOW(1)                                          MySQL Database System                                         MYSQLSHOW(1)



NAME
       mysqlshow - display database, table, and column information

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

DESCRIPTION
       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 12.4.5, "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]]]

       o   If no database is given, a list of database names is shown.

       o   If no table is given, all matching tables in the database are shown.

       o   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 4.2.3.3.1, "Command-Line Options that Affect Option-File Handling".

       o   --help, -?

           Display a help message and exit.

       o   --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, beginning with MySQL
           Cluster NDB 6.3.4. It is not available in standard MySQL 5.1 releases.

       o   --character-sets-dir=path

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

       o   --compress, -C

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

       o   --count

           Show the number of rows per table. This can be slow for non-MyISAM tables.

       o   --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'.

       o   --debug-check

           Print some debugging information when the program exits. This option was added in MySQL 5.1.21.

       o   --debug-info

           Print debugging information and memory and CPU usage statistics when the program exits. This option was added in
           MySQL 5.1.14.

       o   --default-character-set=charset_name

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

       o   --host=host_name, -h host_name

           Connect to the MySQL server on the given host.

       o   --keys, -k

           Show table indexes.

       o   --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 5.3.2.2, "End-User Guidelines
           for Password Security". You can use an option file to avoid giving the password on the command line.

       o   --pipe, -W

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

       o   --port=port_num, -P port_num

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

       o   --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".

       o   --show-table-type, -t

           Show a column indicating the table type, as in SHOW FULL TABLES. The type is BASE TABLE or VIEW.

       o   --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.

       o   --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 5.5.6.3, "SSL Command Options".

       o   --status, -i

           Display extra information about each table.

       o   --user=user_name, -u user_name

           The MySQL user name to use when connecting to the server.

       o   --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.

       o   --version, -V

           Display version information and exit.
