Using the Searched CASE Statement


DECLARE

grade CHAR(1);

BEGIN

grade := 'B';



CASE

WHEN grade = 'A' THEN dbms_output.Put_line('Excellent');

WHEN grade = 'B' THEN dbms_output.Put_line('Very Good');

WHEN grade = 'C' THEN dbms_output.Put_line('Good');

WHEN grade = 'D' THEN dbms_output.Put_line('Fair');

WHEN grade = 'F' THEN dbms_output.Put_line('Poor');

ELSE dbms_output.Put_line('No such grade');

END CASE;

END;

-- rather than using the ELSE in the CASE, could use the following

-- EXCEPTION

-- WHEN CASE_NOT_FOUND THEN

-- DBMS_OUTPUT.PUT_LINE('No such grade');
