CREATE TABLE exhibition (Exhibition_ID INT, Year INT, Theme TEXT, Artist_ID INT, Ticket_Price FLOAT)
CREATE TABLE artist (Artist_ID INT, Name TEXT, Country TEXT, Year_Join INT, Age INT)
CREATE TABLE exhibition_record (Exhibition_ID INT, Date TEXT, Attendance INT)

Bar chart x axis name y axis age, and I want to order from high to low by the bars.
SELECT Name, Age FROM artist ORDER BY Name DESC
SELECT "Name", "Age" FROM "artist" ORDER BY "Name" DESC NULLS LAST
