The sample data used in the
world database is
Copyright Statistics Finland,
To enable MySQL users to perform manipulation of this data set using MySQL, the data set is available as a set of three tables:
Country: Information about countries of the
City: Information about some of the cities in
CountryLanguage: Languages spoken in each
Setup files to create the
world database are
available for the
InnoDB storage engine:
world.sql contains SQL statements to create
the database using
world_innodb.sql is similar but creates
InnoDB tables. The columns are the same as
those in the
MyISAM tables, but the
InnoDB tables also implement foreign key
relationships between tables.
Each file is available for download at http://dev.mysql.com/doc/index-other.html.
The following instructions refer to the
world.sql file, which contains
TABLE statements for
MyISAM tables. To
InnoDB tables instead, substitute the
world_innodb.sql file in the instructions
wherever you see
To create the
world database, load the contents
world.sql file into MySQL using the
Change directory to where the
file is located
If your current directory is not the same as the location of the
world.sql file, use a cd
command to change location.
Connect to the MySQL server using the mysql program
At your command-line prompt, issue this command:
mysql -u root -p
This command connects to the server using the MySQL
root account to make sure that you'll have
permission to create the
world database. The
--p option tells mysql to
prompt you for the
root password. Enter the
password when prompted. (Remember that the MySQL
root account is not the same as the operating
root account and probably will have a
world database and select it as
the default database:
In the mysql program, issue the following statements:
CREATE DATABASE world;mysql>
Load the contents of
world.sql into the
SOURCE command to tell
mysql to read and process the contents of
You'll see quite a bit of output as mysql
reads queries from the
world.sql file and
After mysql finishes processing the
world.sql file, try this statement:
SHOW TABLES;+-----------------+ | Tables_in_world | +-----------------+ | City | | Country | | CountryLanguage | +-----------------+
The output should list all three of the tables shown. Depending on
your server configuration,
TABLES may display the table names in lowercase.
If so, use lowercase names whenever you refer to the tables by name
To see the structure of each table, use
TABLE. For example:
SHOW CREATE TABLE Country;mysql>
SHOW CREATE TABLE City;mysql>
SHOW CREATE TABLE CountryLanguage;
