mysql_convert_table_format
MYSQL_CONVERT_TAB(1) MySQL Database System MYSQL_CONVERT_TAB(1)
NAME
mysql_convert_table_format - convert tables to use a given storage engine
SYNOPSIS
mysql_convert_table_format [options] db_name
DESCRIPTION
mysql_convert_table_format converts the tables in a database to use a particular storage engine (MyISAM by default).
mysql_convert_table_format is written in Perl and requires that the DBI and DBD::mysql Perl modules be installed (see Section 2.15, "Perl
Installation Notes").
Invoke mysql_convert_table_format like this:
shell> mysql_convert_table_format [options]db_name
The db_name argument indicates the database containing the tables to be converted.
mysql_convert_table_format supports the options described in the following list.
o --help
Display a help message and exit.
o --force
Continue even if errors occur.
o --host=host_name
Connect to the MySQL server on the given host.
o --password=password
The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL
programs.
Specifying a password on the command line should be considered insecure. See Section 5.3.2.2, "End-User Guidelines for Password
Security". You can use an option file to avoid giving the password on the command line.
o --port=port_num
The TCP/IP port number to use for the connection.
o --socket=path
For connections to localhost, the Unix socket file to use.
o --type=engine_name
Specify the storage engine that the tables should be converted to use. The default is MyISAM if this option is not given.
o --user=user_name
The MySQL user name to use when connecting to the server.
o --verbose
Verbose mode. Print more information about what the program does.
o --version
Display version information and exit.
