Table schema:
CREATE TABLE enroll (class_code VARCHAR); CREATE TABLE department (dept_code VARCHAR, dept_name VARCHAR); CREATE TABLE course (crs_code VARCHAR, dept_code VARCHAR); CREATE TABLE CLASS (class_code VARCHAR, crs_code VARCHAR)

Question: How many students are enrolled in the class taught by some professor from the accounting department?
SQL: SELECT COUNT(*) FROM CLASS AS T1 JOIN enroll AS T2 ON T1.class_code = T2.class_code JOIN course AS T3 ON T1.crs_code = T3.crs_code JOIN department AS T4 ON T3.dept_code = T4.dept_code WHERE T4.dept_name = 'Accounting'
