SELECT L1.loan_number FROM Loan L1 WHERE L1.amount > (SELECT MAX (L2.amount) FROM Loan L2 WHERE L2.branch_name = 'SR Nagar'); The number of rows returned by the query is______________(Answer in integer)

Correct answer 3 to 3 Solution The query consists of an outer query and a subquery. Step 1: Evaluate the subquery SELECT MAX (L2.amount) FROM Loan L2 WHERE L2.branch_name = 'SR Nagar' Filter rows where branch_name is 'SR Nagar': L15: 40000 L22: 25000 L19: 65000 The maximum amount among these is 65000. So, the subquery returns 65000 . Step 2: Evaluate the outer query SELECT L1.loan_number FROM Loan L1 WHERE L1.amount > 65000 Check each row in the Loan table: L11: 90000 > 65000 (True) L14: 50000 > 65000 (False) L15: 40000 > 65000 (False) L22: 25000 > 65000 (False) L23: 80000 > 65000 (True) L25: 70000 > 65000 (True) L19: 65000 > 65000 (False) The rows satisfying the condition are L11, L23, and L25. The number of rows returned is 3. Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
