Convert 2 letter country code to country name

Question

I have a big list of countries, the user selects which country they are from, I then save the 2 letter code to the database. When I later want to display which country that user is from on another page I can get the 2 letter code from the database, but how should I convert it back to the name of the country? It seems such a waste to have a big switch statement?

<select name='country' value={country} onChange={onChange}>
                <option value=''>Select...</option>
                <option value='AX'>Aaland Islands</option>
                <option value='AF'>Afghanistan</option>
                <option value='AL'>Albania</option>
                <option value='DZ'>Algeria</option>
                <option value='AS'>American Samoa</option>
                <option value='AD'>Andorra</option>
                <option value='AO'>Angola</option>
                <option value='AI'>Anguilla</option>
                <option value='AQ'>Antarctica</option>
                <option value='AG'>Antigua And Barbuda</option>

Answer 1

why don't you try to use a SELECT CASE

CASE

WHEN condition1 THEN result1
WHEN condition2 THEN result2
WHEN conditionN THEN resultN
ELSE result

END;
