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 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]]]
· 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. For information about option files
used by MySQL programs, see Section 4.2.6, “Using Option Files”.
· --help, -?
Display a help message and exit.
· --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 only in the version of mysqlshow that is supplied with NDB
Cluster. It is not available in standard MySQL Server 5.5 releases.
· --character-sets-dir=dir_name
The directory where character sets are installed. See Section 10.14, “Character Set
Configuration”.
· --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-character-set=charset_name
Use charset_name as the default character set. See Section 10.14, “Character Set
Configuration”.
· --default-auth=plugin
A hint about the client-side authentication plugin to use. See Section 6.3.6,
“Pluggable Authentication”.
This option was added in MySQL 5.5.10.
· --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.
Before MySQL 5.5.8, file_name must be the full path name to the file. As of MySQL
5.5.8, the name is interpreted relative to the current directory if given as a
relative path name.
· --defaults-file=file_name
Use only the given option file. If the file does not exist or is otherwise
inaccessible, an error occurs. Before MySQL 5.5.8, file_name must be the full path
name to the file. As of MySQL 5.5.8, the name is interpreted relative to the current
directory if given as a relative path name.
· --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.
· --enable-cleartext-plugin
Enable the mysql_clear_password cleartext authentication plugin. (See Section 6.5.1.3,
“Client-Side Cleartext Pluggable Authentication”.)
This option was added in MySQL 5.5.47.
· --host=host_name, -h host_name
Connect to the MySQL server on the given host.
· --keys, -k
Show table indexes.
· --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.
· --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.
· --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=dir_name
The directory in which to look for plugins. 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.
· --port=port_num, -P port_num
The TCP/IP port number to use for the connection.
· --print-defaults
Print the program name and all options that it gets from option files.
· --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”.
· --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.
· --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 6.4.2, “Command Options
for Encrypted Connections”.
· --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.
