Table schema:
CREATE TABLE exhibition_record (exhibition_id VARCHAR, attendance VARCHAR); CREATE TABLE exhibition (exhibition_id VARCHAR, ticket_price VARCHAR)

Question: How many exhibitions have a attendance more than 100 or have a ticket price below 10?
SQL: SELECT COUNT(*) FROM exhibition_record AS T1 JOIN exhibition AS T2 ON T1.exhibition_id = T2.exhibition_id WHERE T1.attendance > 100 OR T2.ticket_price < 10
