Printing different fields that have a common column value

Last Modified: 2020-06-08
I created in mariadb a table “countrystatistic”   with a CountryName varchar(50), PrimaryLanguage varchar(50) and population int(11). I then insert it several countries.

I’m trying to write a query that would print the countries that share the same primary language. Somehow it’s not working out completely. I have this query but this one doesn’t print ALL the coutries with the common language.

SELECT ALL PrimaryLanguage,COUNT(Primarylanguage),CountryName
FROM countrystatistic
GROUP BY PrimaryLanguage
HAVING COUNT(PrimaryLanguage) > 1;


I tried using a lot of queries with Join. I either got only part of the answer or an error this gave me an error:

SELECT DISTINCT A.PrimaryLanguage, A.CountryName, B.CountryName
From countrystatistic A, countrystatistic B
Where A.PrimaryLanguage = B.PrimaryLanguage
AND A.count(PrimaryLanguage) > 1;

Can someone help me with this? Thank you!

Produces the same results as mine and mine only accesses the table once.
