BB_BASKETITEM table to another existing basket's ID to combine the baskets. A block has been constructed to support this page (see the assignment04-07.sql file). However, an exception handler needs to be added to trap the situation of an invalid basket ID being entered for the original basket. In this case, the UPDATE affects no rows but doesn't raise an Oracle error. The handler should display the message "Invalid original basket ID" onscreen. Use an initialized variable named lv_old_num with a value of 30 and another named lv_new_num with a value of 4to provide values to the block. First, verify that no item rows with the basket ID 30 exist in the BB_BASKETITEM table.Assignment 4-8: Processing and Updating a Group of RowsTo help track employee information, a new EMPLOYEE table was added to the Brewbean's database.
