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 13.5.4, “
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:
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
_’), 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. ‘
?’ characters are converted
into SQL ‘
_’ 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:
Display a help message and exit.
The directory where character sets are installed. See Section 5.11.1, “The Character Set Used for Data and Sorting”.
Compress all information sent between the client and the server if both support compression.
Show the number of rows per table. This can be slow for
MyISAM tables. This option was
added in MySQL 5.0.6.
Write a debugging log. The
debug_options string often is
charset_name as the default
character set. See Section 5.11.1, “The Character Set Used for Data and Sorting”.
Connect to the MySQL server on the given host.
Show table indexes.
The password to use when connecting to the server. If you
use the short option form (
cannot have a space between the
option and the password. If you omit the
password value following the
on the command line, you are prompted for one.
Specifying a password on the command line should be considered insecure. See Section 5.9.6, “Keeping Your Password Secure”.
The TCP/IP port number to use for the connection.
The connection protocol to use.
Show a column indicating the table type, as in
SHOW FULL TABLES. The type is
BASE TABLE or
This option was added in MySQL 5.0.4.
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
whether to connect to the server via SSL and indicate
where to find SSL keys and certificates. See
Section 188.8.131.52, “SSL Command Options”.
Display extra information about each table.
The MySQL username to use when connecting to the server.
Verbose mode. Print more information about what the program does. This option can be used multiple times to increase the amount of information.
Display version information and exit.
