MYSQLSHOW(1)                 MySQL Database System                MYSQLSHOW(1)




NAME

       mysqlshow - display database, table, and column information


SYNOPSIS

       mysqlshow [options] [db_name [tbl_name [col_name]]]


DESCRIPTION

       The mysqlshow client can be used to quickly look at which databases
       exist, their tables, and a table’s columns or indexes.

       mysqlshow provides a command-line interface to several SQL SHOW
       statements. The same information can be obtained by using those
       statements directly. For example, you can issue them from the mysql
       client program. See Section 5.4, “SHOW Syntax”.

       Invoke mysqlshow like this:

       shell> mysqlshow [options] [db_name [tbl_name [col_name]]]

       ·  If no database is given, all matching databases are 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.

       Note that in newer MySQL versions, you see only those database, 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) in order 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:

       ·  --help, -?

          Display a help message and exit.

       ·  --character-sets-dir=path

          The directory where character sets are installed. See Section 7.1,
          “The Character Set Used for Data and Sorting”.

       ·  --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’.

       ·  --default-character-set=charset

          Use charset as the default character set. See Section 7.1, “The
          Character Set Used for Data and Sorting”.

       ·  --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.

       ·  --port=port_num, -P port_num

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

       ·  --protocol={TCP | SOCKET | PIPE | MEMORY}

          The connection protocol to use. Added in MySQL 4.1.

       ·  --socket=path, -S path

          The socket file to use when connecting to localhost (which is the
          default host).

       ·  --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 out more information what the program does. This
          option can be used multiple times to increase the amount of
          information.

       ·  --version, -V

          Display version information and exit.
