CREATE TABLE artist (name VARCHAR, artist_id VARCHAR)
CREATE TABLE exhibition (ticket_price INT)

What is the theme and artist name for the exhibition with a ticket price higher than the average?
SELECT T1.theme, T2.name FROM exhibition AS T1 JOIN artist AS T2 ON T1.artist_id = T2.artist_id WHERE T1.ticket_price > (SELECT AVG(ticket_price) FROM exhibition)
SELECT "T1"."theme", "T2"."name" FROM "exhibition" AS "T1" JOIN "artist" AS "T2" ON "T1"."artist_id" = "T2"."artist_id" WHERE "T1"."ticket_price" > (SELECT AVG("ticket_price") FROM "exhibition")
