For example, How many actors have appeared in each musical? why Group by "T1.Musical_ID" instead of "T2.Name". SELECT T2.Name , COUNT(*) FROM actor AS T1 JOIN musical AS T2 ON T1.Musical_ID = T2.Musical_ID GROUP BY T1.Musical_ID
Hi,
Thanks for your report! We will look into these examples and update them in the later version if we think they are wrong as well.
Best, Tao
