CREATE TABLE mission (Mission_ID INT, Ship_ID INT, Code TEXT, Launched_Year INT, Location TEXT, Speed_knots INT, Fate TEXT)
CREATE TABLE ship (Ship_ID INT, Name TEXT, Type TEXT, Nationality TEXT, Tonnage INT)

Return a bar chart showing the total number of each ship type, and I want to list total number from high to low order.
SELECT Type, COUNT(Type) FROM ship GROUP BY Type ORDER BY COUNT(Type) DESC
SELECT "Type", COUNT("Type") FROM "ship" GROUP BY "Type" ORDER BY COUNT("Type") DESC NULLS LAST
