Oracle Performance Tuning, 2nd Edition
by Mark Gurry and Peter Corrigan


Here are the changes from the 12/98 reprint:


{211} 2nd code block, after 4th line, add:

	sal_val >= 8001  Then

      And change the preceding "THEN" to "OR" so the code reads:

	If sal_val <= 2000  OR
	       sal_val >= 8001  THEN
	       RETURN (0);
	    END IF;
