The IT department should be greater than 19,000, while the Administration departments total should be less than 19,000. DECLARE v_salary laryTYPE ; BEGIN SELECT SUM(salary) INTO v_salary FROM employees WHERE department_id 60; DBMS _OUTPUT.

Use a CASE statement. DECLARE v_no_of_countries wf_rrency_codeTYPE ; BEGIN SELECT COUNT (currency_code) INTO v_no_of_countries FROM wf_countries WHERE currency_code 'EUR CASE WHEN v_no_of_countries 10 THEN 'Fewer than 10 countries' WHEN v_no_of_countries BETWEEN (10,20) THEN 'Between 10 and 20 countries' ELSE 'More than 20 countries' END; DBMS _OUTPUT.
