Bowling League Database

1.??Do any team captains have a raw score that is higher than any other member on the team??

(Hint: You find out the top raw score for captains by JOINing teams to bowlers on captain ID and then to bowler scores. Use a HAVING clause to compare the MAX value for all other members from a subquery.)

You can find the solution in CH14_Captains_Who_Are_Hotshots (0 rows). (There are no captains who bowl better than their teammates!)

2.??Display for each bowler the bowler name and the average of the bowler?s raw game scores for bowlers whose average is greater than 155.?

You can find the solution in CH14_Good_Bowlers (17 rows).

3.??List the last name and first name of every bowler whose average raw score is greater than or equal to the overall average score.?

(Hint: We showed you how to solve this in?Chapter 12?in the ?Sample Statements? section with a subquery in a WHERE clause. Now solve it using HAVING!)

You can find the solution in CH14_Better_Than_Overall_Average_HAVING (17 rows).
