NAME

6       mysqlshow - display database, table, and column information
7

SYNOPSIS

9       mysqlshow [options] [db_name [tbl_name [col_name]]]
10

DESCRIPTION

12       The mysqlshow client can be used to quickly see which databases exist,
13       their tables, or a table´s columns or indexes.
14
15       mysqlshow provides a command-line interface to several SQL SHOW
16       statements. The same information can be obtained by using those
17       statements directly. For example, you can issue them from the mysql
18       client program.
19
20       Invoke mysqlshow like this:
21
22           shell> mysqlshow [options] [db_name [tbl_name [col_name]]]
23
24       ·   If no database is given, a list of database names is shown.
25
26       ·   If no table is given, all matching tables in the database are
27           shown.
28
29       ·   If no column is given, all matching columns and column types in the
30           table are shown.
31
32       The output displays only the names of those databases, tables, or
33       columns for which you have some privileges.
34
35       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
46       mysqlshow supports the following options, which can be specified on the
47       command line or in the [mysqlshow] and [client] option file groups.
48       mysqlshow also supports the options for processing option files
49       described.
50
51       ·   --help, -?
52
53           Display a help message and exit.

58
59       ·   --compress, -C
60
61           Compress all information sent between the client and the server if
62           both support compression.
63
64       ·   --count
65
66           Show the number of rows per table. This can be slow for non-MyISAM
67           tables.
68
69       ·   --debug[=debug_options], -# [debug_options]
70
71           Write a debugging log. A typical debug_options string is
72           ´d:t:o,file_name´. The default is ´d:t:o´.
73
74       ·   --debug-check
75
76           Print some debugging information when the program exits.
77
78       ·   --debug-info
79
80           Print debugging information and memory and CPU usage statistics
81           when the program exits.
82
83       ·   --default-auth=name
84
85           Default authentication client-side plugin to use.
86
87       ·   --default-character-set=charset_name
88
89           Use charset_name as the default character set.
90
91       ·   --defaults-extra-file=filename
92
93           Set filename as the file to read default options from after the
94           global defaults files has been read.  Must be given as first
95           option.
96
97       ·   --defaults-file=filename
98
99           Set filename as the file to read default options from, override
100           global defaults files.  Must be given as first option.
101
102       ·   --defaults-group-suffix=suffix
103
104           In addition to the groups named on the command line, read groups
105           that have the given suffix.
106
107       ·   --host=host_name, -h host_name
108
109           Connect to the MariaDB server on the given host.
110
111       ·   --keys, -k
112
113           Show table indexes.
114
115       ·   --no-defaults
116
117           Do not read default options from any option file. This must be
118           given as the first argument.
119
120       ·   --password[=password], -p[password]
121
122           The password to use when connecting to the server. If you use the
123           short option form (-p), you cannot have a space between the option
124           and the password. If you omit the password value following the
125           --password or -p option on the command line, mysqlshow prompts for
126           one.
127
128           Specifying a password on the command line should be considered
129           insecure. You can use an option file to avoid giving the password
130           on the command line.
131
132       ·   --pipe, -W
133
134           On Windows, connect to the server via a named pipe. This option
135           applies only if the server supports named-pipe connections.

138
139           Directory for client-side plugins.
140
141       ·   --port=port_num, -P port_num
142
143           The TCP/IP port number to use for the connection.
144
145       ·   --protocol={TCP|SOCKET|PIPE|MEMORY}
146
147           The connection protocol to use for connecting to the server. It is
148           useful when the other connection parameters normally would cause a
149           protocol to be used other than the one you want.
150
151       ·   --print-defaults
152
153           Print the program argument list and exit.  This must be given as
