A bar chart for what are the number of the countries of mountains with height bigger than 5000?, could you show in descending by the Country?
SELECT Country, COUNT(Country) FROM mountain WHERE Height > 5000 GROUP BY Country ORDER BY Country DESC
SELECT "Country", COUNT("Country") FROM "mountain" WHERE "Height" > 5000 GROUP BY "Country" ORDER BY "Country" DESC
