Table schema:
CREATE TABLE Customers (customer_id VARCHAR, customer_details VARCHAR); CREATE TABLE Customer_Events (customer_id VARCHAR)

Question: What are the id and details of the customers who have at least 3 events?
SQL: SELECT T1.customer_id, T1.customer_details FROM Customers AS T1 JOIN Customer_Events AS T2 ON T1.customer_id = T2.customer_id GROUP BY T1.customer_id HAVING COUNT(*) >= 3
