IP-Country DB Tables

hi guys,

I'm setting up a system which detects what country a user is from by running a query on the IP-to-Country database which i downloaded as a CSV file from .

I found a script which queries the database using the following syntax:
$country_query  = "SELECT country_code2,country_name, FROM iptoc ".
         "WHERE IP_FROM<=inet_aton('$REMOTE_ADDR') ".
          "AND IP_TO>=inet_aton('$REMOTE_ADDR') ";

The CSV file has the following layout:

"33996344","33996351","GB","GBR","UNITED KINGDOM"
"50331648","69956103","US","USA","UNITED STATES"

The documentation for the CSV file states that " The CSV file contains four fields:

    * Begining of IP address range
    * Ending of IP address range
    * Two-character country code based on ISO 3166
    * Three-character country code based on ISO 3166
    * Country name based on ISO 3166 "

So how should i setup my database tables/fields?  Obviously i have to have an ID field which auto increments, and i will be adding a field for paths for flags, but what other fields should i have? This is the SQL i'm working with now

CREATE TABLE `tables` (
`country_code2` INT( 2 ) NOT NULL ,
`country_code3` INT( 3 ) NOT NULL ,
`country_name` VARCHAR( 55 ) NOT NULL ,
`flag` INT( 12 ) NOT NULL ,
PRIMARY KEY ( `id` )
) CHARACTER SET = latin1;

Also how do i import all the values from the CSV file? I've never used one before.
