MYSQLSHOW(1) MySQL Database System MYSQLSHOW(1)
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 12.4.5, "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] option file groups. mysqlshow also supports the options for
processing option files described at Section 18.104.22.168.1, "Command-Line Options that Affect
o --help, -?
Display a help message and exit.
o --character-sets-dir=path, -c
The directory where character sets are installed. See Section 9.5, "Character Set
o --compress, -C
Compress all information sent between the client and the server if both support
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'.
Print some debugging information when the program exits. This option was added in
Print debugging information and memory and CPU usage statistics when the program
exits. This option was added in MySQL 5.1.14.
Use charset_name as the default character set. See Section 9.5, "Character Set
Set filename as the file to read default options from after the global defaults files
has been read. Must be given as first option.
Set filename as the file to read default options from, override global defaults files.
Must be given as first option.
o --host=host_name, -h host_name
Connect to the MySQL server on the given host.
o --keys, -k
Show table indexes.
Do not read default options from any option file. This must be given as the first
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 22.214.171.124, "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 via 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.
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 allowable values, see Section 4.2.2, "Connecting to
the MySQL Server".
Print the program argument list and exit. This must be given as the first argument.
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.
Options that begin with --ssl specify whether to connect to the server via SSL and
indicate where to find SSL keys and certificates. See Section 126.96.36.199, "SSL Command
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.
