6 mysqlshow - display database, table, and column information
7
9 mysqlshow [options] [db_name [tbl_name [col_name]]]
10
12 The mysqlshow client can be used to quickly see which databases exist,
13 their tables, or a table's columns or indexes.
14 mysqlshow provides a command-line interface to several SQL SHOW
16 statements. See Section 5.4, “SHOW Syntax”. The same information can be
17 obtained by using those statements directly. For example, you can issue
18 them from the mysql client program.
19 Invoke mysqlshow like this:
21 shell> mysqlshow [options] [db_name [tbl_name [col_name]]]
23 · If no database is given, a list of database names is shown.
25 · If no table is given, all matching tables in the database are shown.
27 · If no column is given, all matching columns and column types in the
29 table are shown.
30 The output displays only the names of those databases, tables, or
33 columns for which you have some privileges.
34 If the last argument contains shell or SQL wildcard characters (‘*’,
36 ‘?’, ‘%’, or ‘_’), only those names that are matched by the wildcard
37 are shown. If a database name contains any underscores, those should be
38 escaped with a backslash (some Unix shells require two) to get a list
39 of the proper tables or columns. ‘*’ and ‘?’ characters are converted
40 into SQL ‘%’ and ‘_’ wildcard characters. This might cause some
41 confusion when you try to display the columns for a table with a ‘_’ in
42 the name, because in this case, mysqlshow shows you only the table
43 names that match the pattern. This is easily fixed by adding an extra
44 ‘%’ last on the command line as a separate argument.
45 mysqlshow supports the following options:
47 · --help, -?
49 Display a help message and exit.
51 · --character-sets-dir=path
53 The directory where character sets are installed. See Section 8.1,
55 “The Character Set Used for Data and Sorting”.
56 · --compress, -C
58 Compress all information sent between the client and the server if
60 both support compression.
61 · --count
63 Show the number of rows per table. This can be slow for non-MyISAM
65 tables. This option was added in MySQL 5.0.6.
66 · --debug[=debug_options], -# [debug_options]
68 Write a debugging log. The debug_options string often is
70 ´d:t:o,file_name'.
71 · --default-character-set=charset_name
73 Use charset_name as the default character set. See Section 8.1, “The
75 Character Set Used for Data and Sorting”.
76 · --host=host_name, -h host_name
78 Connect to the MySQL server on the given host.
80 · --keys, -k
82 Show table indexes.
84 · --password[=password], -p[password]
86 The password to use when connecting to the server. If you use the
88 short option form (-p), you cannot have a space between the option
89 and the password. If you omit the password value following the
90 --password or -p option on the command line, you are prompted for
91 one.
92 Specifying a password on the command line should be considered
94 insecure. See Section 6.6, “Keeping Your Password Secure”.
95 Specifying a password on the command line should be considered
97 insecure. See Section 6.6, “Keeping Your Password Secure”.
98 · --port=port_num, -P port_num
100 The TCP/IP port number to use for the connection.
102 · --protocol={TCP|SOCKET|PIPE|MEMORY}
104 The connection protocol to use.
106 · --show-table-type, -t
108 Show a column indicating the table type, as in SHOW FULL TABLES. The
110 type is BASE TABLE or VIEW. This option was added in MySQL 5.0.4.
111 · --socket=path, -S path
113 For connections to localhost, the Unix socket file to use, or, on
115 Windows, the name of the named pipe to use.
116 · --ssl*
118 Options that begin with --ssl specify whether to connect to the
120 server via SSL and indicate where to find SSL keys and certificates.
121 See Section 6.7.3, “SSL Command Options”.
122 · --status, -i
124 Display extra information about each table.
126 · --user=user_name, -u user_name
128 The MySQL username to use when connecting to the server.
130 · --verbose, -v
132 Verbose mode. Print more information about what the program does.
134 This option can be used multiple times to increase the amount of
135 information.
136 · --version, -V
138 Display version information and exit.
