CREATE  FUNCTION PricePerHour (Price REAL, Per VARCHAR(5))  
RETURNS REAL 
DETERMINISTIC

BEGIN 
DECLARE t REAL;
IF Price IS NOT NULL AND Per IS NOT NULL

IF Per='hour' THEN SET t=Price ; END IF;
IF Per='day' THEN SET t=Price/24; END IF;
IF Per='week' THEN SET t=Price/7/24; END IF;

IF Per='year' THEN SET t=Price/365/30/24; END IF;

RETURN t;
END IF;
