what is the flag field for?

[singleseeker]

Hi, I realized every table has a flag field in sql. What is this for?

Hey there, @singleseeker! Great to see you diving deeper into the details of the countries-states-cities-database. How have you been? 🌍✨

In the countries-states-cities-database, the "flag" field in each table is used to store the emoji representation of the country's flag. This is based on the PHP script (scripts/export_csc_npm.php) where the "flag" field is assigned the value from the "emoji" column of the countries table in the database:

$countriesArray[$i]['flag'] = $row['emoji'];

This means that for each country fetched from the database, its flag is represented by an emoji, which is stored in the "emoji" column and then assigned to the "flag" field in the $countriesArray. This array is later exported to a JSON file, making the emoji representation of the flag accessible for each country in the JSON output.

The data type of the "flag" field is a string, as it is being assigned the value of $row['emoji'], which suggests that it is storing emoji characters representing the flags.

You can find more details about the structure of the tables in the countries-states-cities-database in the sql/countries.sql file.

I hope this clarifies your question. If you have any more questions or need further clarification, feel free to ask.
