Description
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 13.7.5, "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]]]
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 4.2.3.4, "Command-Line Options that Affect Option-
File Handling".

MySQL Database System MYSQLSHOW(1)
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. It is not
available in standard MySQL Server 5.5 releases.
o --character-sets-dir=path
The directory where character sets are installed. See
Section 10.5, "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.
o --debug-info
Print debugging information and memory and CPU usage
statistics when the program exits.
o --default-character-set=charset_name
Use charset_name as the default character set. See
Section 10.5, "Character Set Configuration".
o --default-auth=plugin
The client-side authentication plugin to use. See
Section 6.3.6, "Pluggable Authentication".
MySQL 5.5 Last change: 03/22/2013 2
MySQL Database System MYSQLSHOW(1)
This option was added in MySQL 5.5.10.
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 6.1.2.1, "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 --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 6.3.6,
"Pluggable Authentication".
This option was added in MySQL 5.5.10.
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".
MySQL 5.5 Last change: 03/22/2013 3
MySQL Database System MYSQLSHOW(1)
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 6.3.8.4, "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.
