After a row is inserted in table “inventory”, the “itemid”, the insertion time, and the action is inserted in table “Inventory_history”. The action is set to ‘add an item’. The oldprice is set to null. Test your trigger by inserting a row into Inventory and displaying the contents of Inventory_history. (2) Create a trigger “change_quantity” on table “Transaction”. The trigger is fired after a row is inserted in table “Transaction”. After a row is inserted in table “Transaction”, update the “quantity” in table “Inventory”.
