An analyst in the quality assurance office reviews the time lapse between receiving an order and shipping an order. Any orders that have not been shipped within a day of the order being placed are investigated. Create a function named ORD_SHIP_SF that calculates the number of days between the date the basket was created and the shipping date. The function should return a character string that indicates "OK" if the order was shipped within a day or "CHECK" if it was not. The IDSTAGE column of the BB_BASKETSTATUS table indicates the item is shipped with a value of 5 and the DTSTAGE column is the shipping date. The TDORDERED column of the BB_BASKET table is the order date. Use the function in an anonymous block that uses a host variable to receive the basket id to check basket 3.
