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. For information about option files, see Section 4.2.6, "Using
Option Files".
o --help, -?
Display a help message and exit.
o --bind-address=ip_address
On a computer having multiple network interfaces, use this option
to select which interface to use for connecting to the MySQL
server.
This option is supported beginning with MySQL 5.6.1.
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 6.3.7,
"Pluggable Authentication".
This option was added in MySQL 5.6.2.
o --defaults-extra-file=file_name
Read this option file after the global option file but (on Unix)
before the user option file. If the file does not exist or is
otherwise inaccessible, an error occurs. file_name is interpreted
relative to the current directory if given as a relative path name
rather than a full path name.
o --defaults-file=file_name
Use only the given option file. If the file does not exist or is
otherwise inaccessible, an error occurs. file_name is interpreted
relative to the current directory if given as a relative path name
rather than a full path name.
o --defaults-group-suffix=str
Read not only the usual option groups, but also groups with the
usual names and a suffix of str. For example, mysqlshow normally
reads the [client] and [mysqlshow] groups. If the
--defaults-group-suffix=_other option is given, mysqlshow also
reads the [client_other] and [mysqlshow_other] groups.
o --host=host_name, -h host_name
Connect to the MySQL server on the given host.
o --keys, -k
Show table indexes.
o --login-path=name
Read options from the named login path in the .mylogin.cnf login
file. A "login path" is an option group that permits only a limited
set of options: host, user, and password. Think of a login path as
a set of values that indicate the server host and the credentials
for authenticating with the server. To create the login file, use
the mysql_config_editor utility. See mysql_config_editor(1). This
option was added in MySQL 5.6.6.
o --no-defaults
Do not read any option files. If program startup fails due to
reading unknown options from an option file, --no-defaults can be
used to prevent them from being read.
The exception is that the .mylogin.cnf file, if it exists, is read
in all cases. This permits passwords to be specified in a safer way
than on the command line even when --no-defaults is used.
(.mylogin.cnf is created by the mysql_config_editor utility. See
mysql_config_editor(1).)
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 6.3.7, "Pluggable Authentication".
This option was added in MySQL 5.6.2.
o --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
o --print-defaults
Print the program name and all options that it gets from option
files.
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 --secure-auth
Do not send passwords to the server in old (pre-4.1) format. This
prevents connections except for servers that use the newer password
format. This option is enabled by default; use --skip-secure-auth
to disable it. This option was added in MySQL 5.6.17.
Note
Passwords that use the pre-4.1 hashing method are less secure
than passwords that use the native password hashing method and
should be avoided. Pre-4.1 passwords are deprecated and support
for them will be removed in a future MySQL release. For account
upgrade instructions, see Section 6.3.8.3, "Migrating Away from
Pre-4.1 Password Hashing and the mysql_old_password Plugin".
o --shared-memory-base-name=name
On Windows, the shared-memory name to use, for connections made
using shared memory to a local server. The default value is MYSQL.
The shared-memory name is case sensitive.
The server must be started with the --shared-memory option to
enable shared-memory connections.
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 6.3.10.4, "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.
