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 5.4, lqSHOW Syntaxrq. 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 (oq*cq, oq?cq, oq%cq, or oq_cq), 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. oq*cq and oq?cq characters are converted into SQL oq%cq and oq_cq wildcard characters. This might cause some confusion when you try to display the columns for a table with a oq_cq 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 oq%cq last on the command line as a separate argument.

mysqlshow supports the following options:

--help, -?

Display a help message and exit.


The directory where character sets are installed. See Section 9.1, lqThe Character Set Used for Data and Sortingrq.

--compress, -C

Compress all information sent between the client and the server if both support compression.

--debug[=debug_options], -# [debug_options]

Write a debugging log. The debug_options string often is 'd:t:o,file_name'.


Use charset_name as the default character set. See Section 9.1, lqThe Character Set Used for Data and Sortingrq.

--host=host_name, -h host_name

Connect to the MySQL server on the given host.

--keys, -k

Show table indexes.

--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, you are prompted for one.

Specifying a password on the command line should be considered insecure. See Section 7.6, lqKeeping Your Password Securerq.

Specifying a password on the command line should be considered insecure. See Section 7.6, lqKeeping Your Password Securerq.

--port=port_num, -P port_num

The TCP/IP port number to use for the connection.


The connection protocol to use. Added in MySQL 4.1.

--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 7.7.3, lqSSL Command Optionsrq.

--status, -i

Display extra information about each table.

--user=user_name, -u user_name

The MySQL username 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.
