Try this...
DECLARE
CURSOR c_sales IS
SELECT *
FROM sales
ORDER BY sales desc;
r_sales c_sales%rowtype;
l_count NUMBER := 0;
BEGIN
OPEN c_sales;
DBMS_OUTPUT.PUT_LINE( 'Customer' || ' ' || 'Sales' );
WHILE l_count < 3 LOOP
FETCH c_sales INTO r_sales;
DBMS_OUTPUT.PUT_LINE( r_sales.customer || ' ' || r_sales.sales );
l_count := l_count + 1;
END LOOP;
CLOSE c_sales;
END;
/
I did it as a pl/sql block because you can't be fancy (well not in 7.3.4)
and use ROWNUM with an ORDER BY. I was going to
suggest just doing:
SELECT *
FROM sales
WHERE rownum < 4
ORDER BY sales DESC;
But alas, this doesn't work...try the above, it's nasty but quick...
HTH,
Kev.
