Can you tell me about course ACCT-211?
select * from class where crs_code = 'ACCT-211'
How many students are enrolled in this class?
select count(*) from class as t1 join enroll as t2 on t1.class_code = t2.class_code where t1.crs_code = 'ACCT-211'
What are their corresponding first names?
select t3.stu_fname from class as t1 join enroll as t2 on t1.class_code = t2.class_code join student as t3 on t2.stu_num = t3.stu_num where t1.crs_code = 'ACCT-211'
