On occasion, some of Brewbean's customers mistakenly leave an item out of a basket already checked out, so they create a new basket containing the missing items. However, they request that the baskets be combined so that they are not charged extra shipping. A screen has been developed to allow an employee to modify the basket id of items in the BB_BASKETITEM table to another to another existing basket to combine the baskets. A block has been constructed to support this screen and can be found at the end of this question.

First verify that no item rows exist in the BB_BASKETITEM table with a basket id of 30.
BEGIN UPDATE bb_basketitem SET idBasket = :g_new WHERE idBasket = :g_old; END; /
